A tutorial lesson in colour, with pictures that move and a teacher's voice to explain. Press Play on each part and watch together. This lesson is about number bonds: a whole number splits into two parts, and two parts join to make a whole.

Level 1
First steps: split a whole into two parts, join two parts to make a whole, and say the bond out loud.
Level 1 · Worked example
A whole splits into parts — bananas
A worked example — watch how it is done, step by step.
Level 1 · Example 2
Find the missing part — strawberries
The same kind of question, with strawberries. One number is missing.
Level 1 · Example 3
Two parts make a whole — balloons
This time the two parts come together to make the whole.
Level 1 · Missing part
Find the missing part
You know the whole and one part. Find the other part: peppers, pumpkins and pears.
Level 1 · Joining parts
Two parts make a whole
Put the two parts together and find the whole: ice creams, cubes and paper clips.
Level 1 · Picture stories
Count the parts, say the whole
Look at each picture. Count each part, then say how many there are altogether.
Level 1 · Say the bond
Say it with "and"
Say the bond in a sentence: "__ and __ make __."
Level 1 · Show the parts
Circle the parts
The bond tells you the parts. Circle groups of objects to show the parts.
Level 1 · Dots
What numbers make 5? What numbers make 6?
Draw the missing dots, then complete the number bond.
Level 2
One step more: build the bonds of 7, 8, 9 and 10, and tell number stories from pictures.
Level 2 · Bonds of 7 and 8
Number bonds of 7 and 8
Cubes in a row show the parts of 7. Then shells, candy canes and cupcakes show the parts of 8.
Level 2 · Bonds of 9 and 10
Number bonds of 9 and 10
Butterflies on flowers make 9. Birds on a branch make 10. Some fly away — count the parts.
Level 2 · Number stories
Number stories
Look at the picture carefully. Complete the number story and the number bond.
Level 3
A hard one: problem solving — think first, then add the parts step by step.
Level 3 · Problem solving
Squirrel Joe collects nuts
A problem to solve — Joe the squirrel must collect 9 nuts. Find a path that makes 9.
