Suitable for Grades: 3rd Grade
CCSS: 3.OA.A.3, 3.OA.A.4
CCSS Description: Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.1
Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = � ÷ 3, 6 × 6 = ?.
Students will use number lines to count beyond 1 in tenths and fifths throughout this worksheet. Section A begins with a recap as pupils label interval gaps on number lines up to 1 in tenths, fifths, halves and quarters.
In section B the number lines extend to 2 or 3 and go up in tenths. Pupils will label interval gaps on the number line, draw arrows to 1.3 and 2.7 and state what number an arrow is pointing to. Section C is the same however, the number lines go up in fifths.
