identifying combinations- with the Numblox iPad app

The First Grade Butterflies are developing their understanding of numbers and operations in base ten and their algebraic thinking as mathematicians.

Using the Numblox iPad app, the first graders cooperatively use number rods to identify combinations of a quantity.

After the initial introduction of the Numblox app and number rods, the Butterflies cooperatively explored the Numblox app with their math partner (while in the learning circle) to identify combinations of ten.

As various Butterfly math partners shared combinations and strategies used with the class, a "shared" chart of the combinations identified for ten was created on the SMARTboard and students participated in a discussion of the strategies shared.

Utilizing the Numblox app, the math partners apply strategies to identify combinations of a quantity.

Supporting students' development of recognizing and using the mathematical symbols for addition (+) and equality (=) to create, solve, and/or explain thinking, the Butterfly partners record combinations for a determined quantity in equations (for example- 7+2=9).
