Misconceptions Potential misconception

Addressing the misconception

The pupil might not understand which digit in the number to look at to determine whether to round up or down.

•

e.g. 829 rounded to the nearest 100 is 900 (pupil is using last digit to round incorrectly)

Show number on a number line and ask them which multiple of 10 the number is between and how they decide which multiple is nearer to the number. Ask them which digit helps them decide.

• • • • • •

•

Use materials to represent the amounts. This could be cubes, arrow cards, counters or money.

•

Refer back to Place Value Units

•

The pupil might not understand the convention for rounding up if a digit is five or more.

•

Show number on a number line and allow them to explore which multiple is nearer on either side. Explain that we usually round up when the digit is five or more.

•

The pupil always rounds up, e.g. 62 rounded to the nearest ten is 70.

•

Show number on a number line and ask them which multiples the number is between and how they decide which multiple is nearer to the number. Ask them which digit helps them decide.

The pupil thinks rounding is just changing the numbers to zero, e.g. 587 rounded to the nearest 100 is 500

•

Show number on a number line and ask them which multiples the number is between and how they decide which multiple is nearer to the number. Ask them which digit helps them decide.

The pupil might not understand what each digit in a number represents

Teaching ideas Unit 1. Rounding whole numbers to the nearest 10 • • • • • •

Take a pack of numeral cards to 100 and shuffle them. Ask a child to pick one and tell you the number. Find the numeral on a number line to 100. Then ask what multiples are on either side of the number – can they find them on the number line? For example, if you picked 32, the multiples of 30 and 40 are the multiples of ten either side. Which is nearer to the number?

In this case 32 is nearer to 30, so we round down. Repeat with lots of different examples, rounding up and down. Discuss what happens if we have a number ending with 5 – explain that we u in this case, although it depends on the particular context. For instance if we were measuring materials to build a fence there may b we would always round down to make sure the length would not be between posts. Or if we wanted to buy tickets that cost £10 each and a group had £65, we round down to the nearest ten because we can’t use the £5 to buy anothe So there may be some particular contexts where we would always round d up, but otherwise the rule is that for numbers 5 and over we round up. Ask for examples why we might round to the nearest ten in daily money, directions. Extend to 3 digit and 4 digit numbers once confident.

Unit 2. Rounding whole numbers to the nearest 100 • •

Check understanding of rounding to the nearest 10 for a range of number Ask questions such as “What is 88 rounded to the nearest ten? How about 739 do I look at to decide? If I think of a number and round it up to 50 – what could numbers be?” Draw an empty number line on the whiteboard, e.g._______________379 Ask children what the multiples of 100 on either side would be. Ask them to write them in on the number line. Which multiple of 100 is nearer to 379? Discuss how they know. Explain that we round to the nearest 100 by finding the closest multiple o Repeat with different examples. Discuss what happens when a number ends in 50 – explain that we usua this case, although it depends on the particular context. Extend to 4 digit numbers once confident.

Investigating Dinosaurs is a very popular topic in the Early Years. This assessment is suitable for use with children who have carried out class-based topic work relating to dinosaurs. Resources and materials previously used within the topic (concrete, pictorial and in story form) will provide familiar contexts and enable children to demonstrate their understanding and apply their knowledge. However, some of the tasks could be used without prior knowledge of dinosaurs.

Resources Resources provided online: Dot cards 1–10 Alien pictures • Gem resource sheet

Resources Resources provided online: A range of 2D shapes • Pictures of dinosaurs • Dinosaur wrapping paper Resources needed and available in the setting: 3D toy dinosaurs • Selection of fiction and non-fiction books pertaining to dinosaurs • Word bank of dinosaur names

Questions 1. Look at the numbers in the rockets. Write in the missing numbers. 2. Look at the numbers in the spaceships. Write in the missing numbers. 3. Write the following numbers in the moons – thirteen, zero, twenty, twelve, eight.

Answer: 5, 6, 7, 8, 9, 10, 11, 12 and 22, 23, 24, 25, 26, 27, 28, 29 On track • The child writes each missing number correctly and completes the forward sequence accurately and confidently. Further learning required • The child omits a number or numbers, especially when crossing a decade or in the early teens. • They mix up the number sequence. • They reverse the digits when writing some numbers from 12 to 30; for example, the child writes 15 as 51. • They require a visual support – for example, a number track – to help them complete the task. On track • The child writes each missing number correctly and completes the backwards sequence accurately and confidently. Further learning required • The child omits a number or numbers, for example when bridging 10. • They mix up the number sequence. • They reverse the digits when writing some numbers from 20–10; for example, the child writes 15 as 51. • They require a visual support – for example, a number track – to complete the task. On track • The child will immediately link each oral number word with its corresponding numeral and write it correctly. Further learning required • The child may be able to connect the oral number word with its symbol for one-digit numbers but find two-digit numbers more challenging, most commonly reversing digits; for example, writing 13 as 31. • They require a visual support – for example, a number track – to complete the task. On track • The child understands that the numbers symbolise quantities and can use this knowledge to confidently order the numbers. Further learning required • The child regards each digit in the numbers 12 and 19 as separate and so orders the numbers as follows: 1, 1, 2, 5, 8, 9. • They disregard the ‘ones’ digit in 2-digit numbers and so believe that 12 and 19 have the same value and are both ‘the smallest number’. • They need to use the 0–20 counting sequence to order the numbers. • They require a visual support – for example, a number track – to complete the task.

Experiences and Outcomes •

I can use my knowledge of the sizes of familiar objects or places to assist me when making an estimate of measure. (MNU 2-11a)

•

I can use the common units of measure, convert between related units of the metric system and carry out calculations when solving problems. (MNU 2-11b)

•

I can explain how different methods can be used to find the perimeter and area of a simple 2D shape or volume of a simple 3D object. (MNU 2-11c)

There Enabling prompt is an extension activity Pupils who are struggling to make a start on the problem may be encouraged to draw a 22 cm by 10 cm rectangle, or be given the rectangle already drawn on centimetre square paper. They can also be givenfor those working above some pre-cut 6 cm by 4 cm rectangles.

Extension activity Let’s go!

Amman and Isla have a different rectangular piece of plastic. It measures 28 cm by 22 cm. They are going to cut out smaller rectangles measuring 10 cm by 6 cm from their piece of plastic so that some larger rips can be repaired.

When introducing the problem, the teacher can pose the question “Why do Findlay and Nuria want to cut the maximum number of rectangles?”. This will generate some discussion of reducing waste.

6 cm

Finlay and Nuria are repairing some small rips in the plastic covering of the school polytunnel. They have a rectangular piece of plastic measuring 22 cm by 10 cm which they intend to cut into smaller rectangles to use as patches. The smaller rectangles will each measure 6 cm by 4 cm. Finlay and Nuria want to cut the maximum number of 6 cm by 4 cm rectangles from the larger 22 cm by 10 cm rectangle.

Number, Money and Measure

Let’s discuss!

Let’s check!

When a range of solutions have been offered, the teacher should begin to facilitate discussion of these using prompts like: • Do all of the rectangles need to be lying the same way? •

Let’s Check gives solutions to the problem

✔

9 smaller rectangles can be cut out in this way:

If you arrange the rectangles in a different way, can you cut more out?

Using a visualiser, or similar, to display different solutions for discussion will be useful. The teacher can use a number of pre-cut 6 cm by 4 cm rectangles and the outline of a 22 cm by 10 cm rectangle to model different solutions and to demonstrate how moving the smaller rectangles around within the outline of the larger rectangle can result in different solutions. Some pupils may see the relationship between the dimensions of the smaller rectangle and the larger rectangle and use this as they decide where to place the smaller rectangles within the larger rectangle. Some pupils may work with areas immediately, using number facts to calculate the area of the large rectangle and the area of the small rectangle then dividing. This would provide an opportunity to discuss the real-life context and emphasise the importance of showing how the smaller rectangles can be cut out.

Note that rotations of this solution might be offered. Two examples are shown below. This provides valuable opportunities to discuss the real-life context.

If the most efficient solution (fig. 1) is not reached, it is likely that solutions like fig. 2 will be offered as the ‘best’ way to cut out the rectangles.

Let’s Discuss gives pupils different strategies to solve the problem independently, in pairs or groups. There are prompts for teachers as well as methods pupils may use

In the extension activity, 10 smaller rectangles can be cut out as shown here. Note that this is the same solution rotated.

Fig. 1

Fig. 2

For some pupils this might be a reasonable conclusion to the problem. For others though the teacher might direct the discussion towards the area ‘left over’ to encourage pupils to see that there may be a more efficient solution. Prompts like these may be useful: •

Do you think there is enough plastic left over to make another rectangle? How can you check this?

•

It is interesting that 6 cm and 4 cm added together make 10 cm (and/or 6 cm + 6 cm + 6 cm + 4 cm makes 22 cm and/or 6 cm + 4 cm + 4 cm + 4 cm + 4 cm makes 22 cm)

Some pupils might ask if the unused pieces of plastic can be collected and used to repair a rip. The teacher might use this as an opportunity to ask the pupils to consider how strong the smaller pieces might be and also how efficient this would be in terms of the work involved.

Let’s reflect! After pupils have had an opportunity to grapple with the problem they should be brought together and given an opportunity to share their strategies and discuss their progress towards a solution. It is likely that pupils will share approaches that involve them ‘having a go’, evaluating their solution, breaking down one attempt in order to look for a better solution, and so on.
