Play select games from the ST Math preschool curriculum for free. Concepts include counting, patterns, addition, and subtraction.

Count sets circles arranged in a variety of ways up to 7 circles.

- Use counting strategies to keep track of the number of circles arranged in a variety of ways and select the same number of circles.
- Levels begin with sets of 2-3 objects and go up to 7 objects.
- Develop 1:1 correspondence and counting strategies.

Count alien ships up to 10 and represent the count on a ten frame.

- Use counting strategies to keep track of the number of alien ships by clicking each one and represent the count on a ten frame.
^{ } - Levels begin with < 5 alien ships and go up to 10 alien ships.
- Develop 1:1 correspondence, counting strategies and model numbers on a ten frame.

Add 1 more to quantities ≤5 and take 1 from quantities ≤5.

- Add or take away a block from the start quantity (left side) by selecting the total number of blocks at the end (right side).
- Develops a foundation for addition and subtraction of 1 within 5.
- Levels start by matching the initial quantity, then adding 1 more block and transition to deciding if 1 more or 1 less is the correct solution.

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.
