Early Algebra for the Interactive Whiteboard:
Expressions and Equality
by Dr. Henry Borenson
This interactive whiteboard application (Promethean, Mimio, etc.), intended for teachers of students in grades 1 - 3, focuses on the relational meaning of equality (CCSS 1.OA.7). Using objects and pictures, students combine like terms, evaluate expressions and determine the missing value to make two expressions equal (CCSS 1.OA.8).
Evaluate 1: 2a + 3p if a = 5 and p = 10.
Example 2: Find the unknown value in 3a - a + 2p - p = 2a + ___
Example 3: 4 + __ + 5 = 10 - 2 + 3
