Use the number line for addition and subtraction within 15 with this snowflake themed set. There are number lines differentiated at two levels of support, 135 clue cards for moving up and moving back to add and subtract, a board game, a printable cut-and-glue response page, and a set of giant sized number cards your students can use to build a number line on the floor and jump to solve the clues. A fun winter activity for first grade math centers, math intervention teachers, and home school!
