FIND THE RIGHT KIND OF PRACTICE

Number bonds & target sums

Find parts that make a whole, including make-ten combinations.

A number bond describes parts and a whole. Making ten is one especially useful case, but a target can also be twelve, twenty, or a changing total.

Choose a fixed-ten game when you specifically want complements to ten. Choose a changing-target game when you want players to recompute the missing part instead of reusing one memorized pair.

How to choose

  • Egg PoolIts matching targets are complements that total ten.
  • Cascade TheoryPlan swaps that create adjacent straight groups totaling ten.
  • Egg ConveyorBuild a carton to its displayed target while visible eggs retain their values.
  • Drop 20Work with combinations totaling twenty instead of ten.

A suggested discussion

write a target as two or more parts and compare two valid combinations.

  • What is the whole, and which parts do you already have?
  • How much is still needed?
  • Does this game always use ten, or does its target change?

Adapt this suggestion to your learner. It is not an implemented game feature or curriculum standard.

Cascade Theory game artwork

Number bonds & target sums

Cascade Theory

Swap neighboring eggs to make straight groups totaling ten. Cleared eggs fall and can set off more clears; aim to empty the board in twenty moves.

  • Identify adjacent numbers that total ten
  • Predict the result of swapping two neighboring positions
  • Consider how gravity and column movement change the next board

Addition

Egg Conveyor

Catch numbered eggs from a moving conveyor and put together the target sum. Exact cartons keep the run going; three overshoots end it.

  • Keep a running sum of selected values
  • Find the amount still needed to reach a target
  • Choose a combination from the values currently available
