Finding addition patterns
http://illuminations.nctm.org/LessonDetail.aspx?ID=L97
A lesson plan for grades 1–2 Mathematics
In this lesson, one of a five-part unit from Illuminations titled “Let’s Learn Those Facts,” a game encourages students to find the sums of two one-digit numbers. Students explore commutativity and examine addition patterns. Then they record known facts on a personal addition chart. Reasoning is a major focus in this lesson.

Mathematics (2004)
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).
- Goal 5: Algebra - The learner will demonstrate an understanding of classification and patterning.
- Objective 5.03: Create and extend patterns, identify the pattern unit, and translate into other forms.
Grade 2
- Goal 1: Number and Operations - The learner will read, write, model, and compute with whole numbers through 999.
- Objective 1.03: Create, model, and solve problems that involve addition, subtraction, equal grouping, and division into halves, thirds, and fourths (record in fraction form).
- Objective 1.05: Create and solve problems using strategies such as modeling, composing and decomposing quantities, using doubles, and making tens and hundreds.
- Goal 5: Algebra - The learner will recognize and represent patterns and simple mathematical relationships.
- Objective 5.01: Identify, describe, translate, and extend repeating and growing patterns.
