Play select games from the ST Math first grade curriculum. Concepts include place value, addition, subtraction, number line, shapes, and more.

Count and represent numbers to 20 using place value.

- Decompose numbers into groups of tens and ones by using visual models.
- Levels begin with representing sets of spaceships ≤10 on a ten frame, then move to representing ≤20 spaceships by creating a set of 10 and 1’s.

Develop strategies for solving addition and subtraction problems.

- Use problem solving strategies to find missing values in visual addition and subtraction situations where blocks are added or subtracted.
- Determine if a situation requires addition or subtraction, or a combination of both.
- Levels begin with finding sums or differences given a visual model, then move to determining which value (a missing addend or subtrahend) is needed.

Estimate and plot numbers on number lines to 20.

- Build the concept of numbers as equidistant points on a line by plotting and estimating numbers to 20.
- Levels start by using number lines to 10 ticked and labeled with all the numbers, then progress to showing only benchmark numbers.
- Apply concepts of numbers on a number line to estimate numbers to 20.

Create a composite shape by arranging the given shapes.

- Compose a given 2-dimensional shape by using smaller shapes.
- Levels begin by simple matching of shapes, then move to more complex problems that require close attention to specific attributes of given shapes.
- Develop spatial strategies for reasoning about angles and sides to compose a larger shape.

Decompose quantities less than 20 into tens and one using visual models and equations.

- Represent numbers 11-19 as a set of 10 and 1’s using ten frame models
- Solve missing addend equations.
- Levels start with finding the missing addend for numbers less than 10 with ten frames, then progress to representing numbers 11-19 using equations in the form 10+ _ (ones).

Create equal groups of tug boats using addition and subtraction strategies.

- Develop addition and subtraction strategies for creating equal groups.
- Levels begin with visual models, then progress to working with numbers to create equivalent sets.

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.
