Title: Relate Addition & Subtraction StudyJam
Description:

The classroom resource provides a video that explains that inverse operations are pairs of mathematical operations, like addition and subtraction, that can undo each other. The video also introduces fact families. After utilizing this resource, the students can complete the short quiz to assess their understanding

Subject: Digital Literacy and Computer Science (K - 2), Mathematics (K - 1)
Title: Model It Up in Google Sheets
Description:

In this learning experience designed for littles (grades Pre-K through 2nd), Christine Pinto, Kindergarten teacher and co-author of Google Apps for Littles,  uses Google Sheets templates to help her students learn basic addition and give them early exposure to equations. Students can "make five", "make ten", "make twenty", following the colors in the Google Sheets cells.

The kids make their models by using single digit numbers according to the color key to color the cells. First, they fill in the blank cells with a color by typing the number that corresponds to the color. For example, they could fill three boxes with green, two with orange. Then they add their equation to the yellow box to show how it makes 5 (3 (green) plus 2 (orange) equals five). Then they check their answer in the blue box following the example.

Learning Outcomes :

• Students will be able to create equations that equal 5, 10, or 20.

• Students will be able to decompose a number and understand the purpose of the equal sign.

• Students will gain a foundational understanding for multiplication.

• Students will be able to write mathematical expressions.
