This hands-on activity is great to help students relate addition and subtraction.
First, give your students an assortment of cubes. They need to use two colors to build as many cube trains as possible. The total number of cubes in the train depends on the number in the top right corner of the worksheet. From there, the students complete one addition equation and one subtraction equation to go along with each cube train. The equations are already scaffolded for students are beginning to understand the relationship between addition and subtraction.
If a student is working on adding to 6, they will be given the worksheet with the 6 in the upper right hand corner. The student will be responsible for building a cube train with 6 cubes and completing the following equations: __ + __ = 6 and 6 - __ = __.
This is a great activity to introduce whole-group and use as an independent center during math time!
This activity can be easily differentiated. You can decide the total number of cubes you want each student to work with. The worksheets allow students to complete the activity for a cube train of 2 to 10 cubes.
