Subtraction With Regrouping through 1,000 - 3 digit subtraction intervention
Subtraction with regrouping (within 1,000) is a concept typically taught in third and fourth grade math classes. It is a critical skill that builds upon both subtraction fact fluency and place value understanding. Students can be taught this skill through a variety of strategies such as number lines, hundreds charts, and base 10 blocks to build conceptual understanding. The eventual goal, however, is that students will be able to fluently and efficiently solve subtraction with regrouping proble

Decomposing Arrays Worksheets
Decomposing arrays using pictures is a strategy that helps students understand the relationship between multiplication and division. Students can use pictures of arrays to decompose, or break down, a multiplication problem into smaller parts. For example, to solve 6 ÷ 2, students can draw a 6 x 1 array and then circle two rows of three objects each to show that 6 can be divided into two equal parts of 3. Using pictures to decompose arrays helps students develop their critical thinking skills and
