Tens and Ones with Spaceships

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.

Push Box Addition and Subtraction

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.

Numbers on a Number Line

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.

Composite Shapes

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.

Making Tens and Ones with Ten Frames

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).

Tug Boats Equal Groups

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.
