# Kindergarten Math Games

Play select games from the ST Math kindergarten curriculum. Concepts include counting, addition, subtraction, comparing numbers, sorting, and classifying.

## Count Objects to 10

Count and match sets of up to 10 objects.
• Develop counting strategies such as 1:1 correspondence and cardinality.
• Levels begin by just clicking on given objects, then progress to selecting equivalent number of squares in the ground.
• As the levels transition, students internalize strategies and connect numerals to the counting sequence.

Develop addition concepts by finding the total number of blocks.
• Add blocks at the start (left side) to the blocks in the middle by selecting the total number of blocks at the end (right side).
• Develop and apply strategies for solving visual addition problems.
• Levels start with sums ≤ 5 by adding up to 2 more blocks and transition to sums up to 10.

## Count Objects to 20

Count sets of alien ships using ten frame models.
• Use counting strategies to keep track of the number of alien ships and apply cardinality (last number counted tells how many) to ten frame models.
• Levels begin with sets of 5 or less and progress to sets of up to 20 aliens.
• Keep track of objects counted and use ten frame models with numerals to represent quantities up to 20.

## Select Box Subtraction

Find the number of blocks left after a set of blocks is taken away.
• Find how many blocks are left after taking away 0 to 5 blocks.
• Levels begin visually and transition into symbolic representations of subtraction.
• Develop strategies for taking away a set of blocks and finding the difference.

## Creature Combinations to 10

Compose number combinations to 10 using visual models.
• Use visual models to compose sets up to 10.
• Develop strategies for finding sums for a given number.
• Levels begin with simple matching of creature legs to shoes, then move to finding different combinations for 10.

## Birds on a Wire Equations

Model addition and subtraction equations using a visual model.
• Use the visual model to represent a given number as birds sitting on a wire, then model adding or subtracting a given number as birds flying onto or off of the wire.
• Develop the concept of addition as ‘adding to’ and subtraction as ‘taking from.'
• Levels begin with modeling sums and differences to 5, then move to 10.
