This lesson teaches students how to calculate total costs of multiple items and make spending decisions based on a fixed budget.

This lesson focuses on identifying US coins (penny, nickel, dime, quarter) and their respective values through visual recognition and matching.

Introduces non-unit fractions by counting multiple shaded parts (e.g., 2 out of 3, 3 out of 4). Focuses on the verbal transition from "one part" to "many parts" while maintaining visual consistency.

Introduces the concept of a unit fraction by identifying 'one part' out of a whole. Focuses on visual recognition of one shaded part and introduces the verbal phrasing 'one out of x' in English and Portuguese.

Focuses on identifying the number of equal parts (2, 3, and 4) in a whole. Introduces the vocabulary for halves, thirds, and fourths through visual counting and symbols, maintaining a low-literacy approach.

A foundational introduction to fractions as equal parts of a whole, specifically designed for students with interrupted education and no literacy. This lesson uses high-visual, low-text materials to assess and build conceptual understanding of partitioning and fair shares.

Students practice adding and subtracting numbers within 20 by using visual strategies like drawing objects or crossing them out. This lesson focuses on conceptual understanding through modeling.

A comprehensive end-of-year math review for 1st grade students, aligned with Illinois Learning Standards. The lesson covers all major domains including Operations, Base Ten, Measurement, and Geometry through minimalist, high-legibility worksheets.

A lesson focused on adding 10 to any 2-digit number using visual base-ten models and mental math strategies. Students explore how the tens digit increases by one while the ones digit remains constant.

A hands-on exploration of geometry and spatial reasoning using tangrams, featuring puzzles across four diverse themes with varying difficulty levels.

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.

A fun introduction to basic shapes through tracing and recognition activities.

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."
