What is Number Builders?
Number Builders is a comprehensive and engaging number support programme for Foundation and Key Stage 1 that brings together flexible lesson resources and an innovative classroom manipulative, n-bars.
Developed by former head teacher Ian Connors, this multi-sensory, highly accessible programme can be implemented in full or to complement your existing maths provision.
Multi-functional, classroom-tested manipulative, n-bars, encourages children to build numbers and explore maths concepts in 3D
Fully editable, downloadable lesson plans, slideshows and activities save time and support confident teaching of number
Short, easy-to-follow training videos demonstrate how to teach a mastery mindset and how to use the resources to their maximum potential
Additional physical classroom resources enable children to perform independent number work
Number Builders comprises a digital subscription, number lines and frames, activity cards and n-bars.
Definitely a resource to consolidate and secure children’s number knowledge… the lessons were sequenced well and accessible for all children.

Provide a concrete representation of number with n-bars
Colour-coded and multi-functional, n-bars can be joined in multiple ways to build various maths models. n-bars can also be used alongside other classroom resources like pencils or modelling clay to boost understanding and improve fine motor skills.
We always aim to teach maths in a practical, concrete way before moving on to the abstract and this manipulative helped us to do that.
South Ossett Infants Academy
Each n-bars pack contains 90 n-bars in complementary colours for number bonds up to 10 and neutral colours for base numbers 1, 5 and 10.
Teach confidently with flexible, downloadable resources
Number Builders lesson plans, teaching resources and training videos are accessible on The Collins Hub, providing unlimited access for both pupils and teachers on whiteboards, computers, tablets and smartphones, inside or outside the classroom.

All additional resources required for each lesson are listed clearly in the plan Sample
Lesson plans are broken down into easy-to-follow steps to keep progress on track
• Slide 1: Revisit the idea of putting large numbers into groups of ten to make counting them easier. Count the tens and the remaining ones.
• Slide 2: Remind the children to count the tens and then the ones. Use number frames and number lines to look at more numbers together.
STEPS
• Slide 3: Vocab: Count in tens to consolidate the vocabulary.
• Slide 4: Look carefully at how the number 73 is made up. Say: We can say that it is seven tens and three ones or that it is 70 and 3. Ask: Is seven tens always 70?
• Slides 5–9: Practise partitioning numbers to complete part-whole models. On Slide 9, ask: Why do we put a zero into the part-whole model for 90?
• Slide 10: Ask the children to talk through their thinking as they complete the partwhole model.
• Slides 11–13: Introduce the activity sheets
PLENARY
• In the plenary, give two children a large single-digit number card each to hold so that they make a two-digit number. Ask: What number have you made? How is it made up? Ask them to swap places and say what the new number is. Ask further questions about this number, for example, is it bigger or smaller than the first number? Is it odd or even?
• Slide 14: Ask the children to close their eyes and ‘see’ the 1–100 frame in their head. Ask: Where do you think the number 50 is? They open their eyes and check if they were right. Ask those children who knew where it was how they knew. Repeat with other numbers and share their strategies. This will consolidate number structure and enhance their understanding of place value.
The teaching resources are fully editable to ensure that your school has complete freedom over how the lessons are taught. ©HarperCollins

Put two groups of n-bars in front of the children. Group 1 equals 15 and group 2 equals 17. 2. Place a whiteboard between the two groups of n-bars. 3. The children find out the total in each group by connecting the n-bars. They can use an n-bar 100-Frame or 0–100 n-bar Line to help them if needed. 4. The children write the numbers on the whiteboard with a gap in between. 5. Next, they write the symbol to make a correct statement, that is: >or < or = . In this example, 15 < 17. 6. Repeat for different numbers. It is important to choose some totals which are equal. Notes, questions and vocabulary Securing an understanding of the symbols is important. It is assumed the children will have already encountered the symbols many times. If required, you can use the n-bars to help the children remember the symbols. Put an n-bar 1 on top of an n-bar 3 and then this on top of an n-bar 5. This makes the arrow head. Rotate the arrow so it forms either < or >. The children can see that the largest number (n-bar 5) is at the widest part of the arrow and the smallest (n-bar 1) is at the point of the arrow. This helps show where the larger number is if you put the arrow head between two amounts. See the picture on the front of the card. -B Y2 y d n 15 N-Bar Y2 Activity Cards.indd 12 0 2 24 07 12/03/2024 09:07 11121314151617181920 12345678910 ©HarperCollinsPublishers Ltd 2024 498 N mb me 2 ndd 1498 Numberframe_20.indd 1 02 2 4 13 0 29/02/2024 13:50
