A lesson plan for grades 1–2 Mathematics
This lesson, the last of a six-lesson unit from Illuminations, reviews the work of the previous lessons and suggests a framework for summative assessment. Students use the mathematical knowledge and skills developed in the previous lessons to demonstrate understanding and the ability to apply that knowledge to playing subtraction games.

Grade 1
- Goal 1: Number and Operations - The learner will read, write, and model whole numbers through 99 and compute with whole numbers.
- Objective 1.03: Develop fluency with single-digit addition and corresponding differences using strategies such as modeling, composing and decomposing quantities, using doubles, and making tens.
- Objective 1.04: Create, model, and solve problems that use addition, subtraction, and fair shares (between two or three).
Grade 2
