A lesson designed to help students recognize and build numbers 10 through 20 by connecting visual quantities (ten-frames and groups of stars) to their symbolic representations.

A foundational math lesson focusing on recognizing numbers 10-20, counting on to 20, and counting backwards from 10. Students embark on a nature-themed journey to build number sense.

A math practice lesson focused on first-grade addition and time-telling skills, themed around the animals of the African savannah.

A comprehensive set of tools for assessing and tracking a student's ability to identify numbers 1 through 20 in randomized order.

Students conduct their own small-group survey, create a bar graph, and solve math problems based on their unique data.

Students use addition and subtraction to answer questions about bar graphs, focusing on "how many more" and "how many fewer."

Students learn to translate tally data into bar graphs, visualizing their pet shop findings.
