Product Description
This package is the second of three developed to help students conceptually understand the meaning of the equal sign (=) as a comparison symbol. This package helps students learn how to find missing numbers in an equation, a critical knowledge to master CC 1.OA.7 and CC 1.OA.8.

The PowerPoint is scaffolded and moves students from linking cubes to using dots to using numbers. Slides are color-coded and animated to increase the students’ understanding and has guiding questions for the teacher. Finally, the PowerPoint is divided into two sections and each section has worksheets with answer keys for additional practice and homework.

Section 1: Students find the missing number counting dots and linking cubes. The slides’ animations guide students’ thought process to make the connections between the concrete representation of the equations and the missing number. Two animated and color-coded examples are provided. Worksheets provide additional practice and homework. (4 pages)

Section 2: Replaces the dots with numbers while still utilizing linking cubes. Two animated and color-coded examples to help students find the missing number. Worksheets are provided for additional practice and homework. (4 pages)

Section 3: Utilizes dots and numbers. Students find the missing number by counting dots. The animation on the slides guide students through the process and helps them make the connections between the concrete representation of the equations, the dots and the missing number. Two animated and color-coded examples are provided. Worksheets provide additional practice and homework.

Section 4: Utilizes numbers instead of dots. Two animated and color- coded examples help students find the missing number. Worksheets are provided for additional practice and homework.

Section 5: Provides students an opportunity to understand the difference between finding the missing number in an equation and checking the answer. A worksheet is provided for students to follow along.

Activity 5.1 and 5.2 Worksheets provide additional practice finding the missing number when the equation has addition on both sides. Students cut the missing number and paste them to make the equations true.

Additional Activities: Activity 6.1, 6.2 and 6.3, provide a mixed review finding the missing number including addition and subtraction. Students cut the missing number and paste them to make the equations true. Ideal for extra practice and homework.

This package includes: PowerPoint (15 slides), Teacher’s Notes with guiding questions and teaching ideas, 38 student pages not including answer key pages.
