How to use this worksheet
- 1
Let your child talk through the logic grid out loud. Saying "Noah has kites, so nobody else has kites" is exactly the reasoning the grid records.
- 2
On "Which One Does Not Belong?", challenge your child to find a reason for every choice. There is no single answer, and arguing for one is the skill.
- 3
Use the four-step boxes for homework word problems too. The "check" step is where most second-grade errors get caught.
