The math worksheet titled "Foundational Addition and Subtraction: Comparing Quantities by Counting Up and Down" provides students with a fun and engaging way to practice foundational addition and subtraction skills by counting up and counting down. Each worksheet features a large group of two or three types of small pictures, like ghosts, clouds, and paddles. Some of these small pictures are captured in overlapping shapes, like triangles and rectangles. There are multiple questions on each page that ask students to identify the number of pictures in a particular shape, in addition to asking the number of a particular type of picture in one shape or not another. Questions ask students to compare quantities, count up, and count down, enabling them to build a firm foundation for the basis of adding and subtracting.

The concept of adding and subtracting using addition and subtraction symbols can be difficult for a first grader to grasp. Instead of diving into the abstract principles of adding and subtracting, it's helpful to first build a foundation by having students practice counting up or counting down. For example, you might ask how many more there are in the number 8 compared to the number 5. Students are able to find the answer by counting up from 5 to 8 or counting down from 8 to 5. Comparing numbers by counting up or down can be done in a variety of engaging ways, like comparing a pile of erasers to a pile of pencils, or the number of students in one area of the classroom compared to another. They get to experience the basis of addition and subtraction, which involves comparing quantities to each other. They also get to see how closely addition and subtraction are related, which teaches them to be flexible when solving future math problems.
