Bonds of 10: Building a Wall

29.1 Addition Building A Wall

Mathematics

Develop the concept of:

  • The whole number 10 being equal to two parts joined together (two-part bond of five).
  • The commutative property of addition.

Develop fluency using bonds of 10 in addition equations, expressed verbally.

Language

  • addition as “add”
  • equals
  • part-part-whole
  • The Commutative Property of Addition: swapping the order of the parts does not alter the size of the whole.

Differentiation

A little easier

Working Memory Support: build a wall
  • Instruct students who are having difficulty to build a bond wall of 10 using one of each block from 1 to 10 and an additional 5 block.
  • Cover this with a piece of paper.
  • Students predict the answer to the subtraction spun, then lift the paper to find the related bond and confirm/correct their answer.
  • Replace the piece of paper covering the blocks in preparation for their next turn.
Working Memory Support: desk visual

These part-part-whole diagrams  can be stuck to the top of student’s desk, as a desk visual, until students are fluent recalling these facts. Students with memory or processing difficulties can benefit from having visuals as permanent prompts.

Bonds of 10 (and doubles) are as essential to Maths as vowels are to English. For this reason there are four different versions of desk visuals for bonds of 10. Choose the one most appropriate for the student. Click the image to download.

This visual shows all the two-part bonds of 10.

This visual shows the more difficult to remember two-part bonds of 10.

This visual is smaller and can be taped to the back of a ruler for discrete use by students who are older or self-conscious about using visual supports. It also contains the most difficult to remember double bonds.  

This visual is the same as the smaller one above, except the bonds of 10 are in dark blue. This is to cater for students who are adverse to pink.
