Teachers’ Notes The idea of Problem Solving activities often conjures up images of numbers and objects that have no direct meaning for students other than teaching the basic problem solving strategies. The activities in this book are designed to present real life problems in a realistic context so as to provide children with situations in which every day problem solving and comprehension skills are required. The activities are based around recurring characters who find themselves exposed to a range of problems that need to be solved; the sorts of problems that students may one day encounter.

Problem Solving Strategies

ew i ev Pr

Teac he r

Most pages include a challenge activity, usually an extension of the main problem, which will further consolidate comprehension skills. Included throughout the book are brainteaser pages which focus on a particular problem solving strategy, highlighted at the foot of the page. These brainteasers can be photocopied and individually glued on to card so as to create a set. Students might like to think up their own brainteasers to add to the set.

There are many strategies for solving every day maths problems. Some of the main problem solving strategies have been explained below. In some cases examples of problems are given where the particular strategy can be applied. Guess and check: Probably the first strategy children might try and definitely the easiest. By making a guess and checking their answer children have a point of reference on which to base all other guesses.

An example: I am thinking of two consecutive numbers that when multiplied give 182. A guess might be to try 14 x 15 which would give 210. Obviously the next guess would try lower numbers. 14 Total

210

w ww

m . u

Act it out: Students quite often need to visualise the problem, especially where people or objects are concerned. Counters, coins and students can be used to help solve the problem.

. te

o c . che e r o t r s super

Some examples: There are 48 players in the darts championships. Each player stays in the competition until they lose a game. How many games must be played to find the club champion? A caterpillar crawls up the tree 2 m every day. Every night it slips back 50 cm. The tree trunk is 10.5 m tall. How long will it take for the caterpillar to reach the top of the trunk? Make a model: When problems cannot be acted out, the next best thing is to make a model using cubes, matches and so on. Make a drawing, diagram or graph: Graphs and diagrams are particularly useful for trying different combinations or clarifying information. An example: Jack has a rectangular field that has an area of 360 m. What are the possible dimensions of the rectangle? Page 4

Ready-Ed Publications

Look for a pattern: This strategy can be used in many number and space activities to help simplify the problem. Number patterns: It takes three matches to make a triangle, 5 matches to make 2 triangles. How many matches are needed to make 3 triangles? Spatial Patterns: How many squares are there on a checker board? Construct a table: By organising data in a more meaningful way children can better see relationships, patterns and possibly missing information. This strategy is best used where different information is given about each person or object in the problem. A table can include all the information and eliminate irrelevant information.

Jess Kelly Max

Tennis

Hockey

ew i ev Pr

An example: Tim, Jess, Max, Jane, Tannie and Kelly each play sport over the weekend. They all play a different sport. Match the person to their sport based on the following: Tim doesn’t like swimming but enjoys cricket. Jess likes tennis more than swimming. Kelly enjoys netball. Max won’t play hockey. Jane doesn’t like cricket or diving. Tannie plays the sport that Max doesn’t like.

Cricket

Diving

Jane

w ww

The solution can then be found through the process of elimination.

. te

m . u

Tannie

Make a list: All possibilities can be listed when using this strategy and again the process of elimination can be used.

o c . che e r o t r s super

An example: You have three T-shirts: red, blue and yellow; and four pairs of jeans: green, black, navy and light blue. How many different combinations can you wear? Restate the problem: This is best used to make sure students fully comprehend the problem and know what they need to do to find the solution. An example: At the supermarket Sarah bought some groceries. All the things she bought were the same price and she bought as many things as the total number of pence she was charged for each item. If her bill was $6.25 how many things did she buy? This could then be rephrased as: How many things can be bought with $6.25 where they all cost the same amount? Ready-Ed Publications

Page 5

Solve a simpler problem: By exploring a simpler problem, an apparently difficult task can be made easier. Students can look for a pattern and then transfer this pattern to the larger problem. An example: There are 20 people at a meeting. Everyone shakes hands with each person once. How many handshakes take place? This could be tried with a group of five and then children can look for a pattern.

r o e t s Bo r e p ok u S

Account for all possibilities: This strategy can be used in addition to some of the strategies already mentioned such as making a list.

Teac he r

ew i ev Pr

An example: Emily is playing Monopoly and wants to buy Park Lane at a cost of $400. She has four $100 notes, ten $50 notes, seventeen $20 notes, eight $10 notes, fifteen $5 notes and six $1 notes. How many different combinations of $400 can she hand over to the banker?

Use logical reasoning: This strategy involves students using what they already know to solve a problem. A solution can be reached when logical reasoning is used to draw conclusions about mathematics. Strategies involve using models, known facts, properties and relationships to explain thinking.

An example: Ann, Brendan, Cathy and Daryl all play an instrument in the school band. They play the tuba, violin, flute and harp. Ann plays the harp and Brendan does not play the violin. If Cathy plays the tuba, what does Daryl play?

Work backwards: This strategy works best when a problem is stated so that the final outcome is clear. In such a case the condition that existed earlier needs to be determined.

Flight departure Delay of one hour and fifteen minutes Arrived two hours early

. te

10.30 10.30 less 1.15 = 9.15 9.15 - 2.00 = 7.15 pm

m . u

An example: Michael arrived at the airport and noticed that he had to wait two hours for his flight. A delay of one hour and fifteen minutes was announced. Michael’s flight eventually departed at 10.30 pm. At what time did Michael actually arrive at the airport?

o c . che e r o t r s super

Tips for Students (Make a wall chart of these points.)

Make sure you understand the problem. Have a go even if you just play around with the problem. Try a variety of strategies. Learn from your mistakes. Keep a record of your working out for the bigger problems so that you can refer back if needed. Check your answers.
