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.

A rigorous lesson for grade 4 on solving multi-step word problems using addition, subtraction, multiplication, and division. Students use 'Detective Toolkit' strategies to interpret complex scenarios and choose correct operations.

A collection of spring-themed math activities focusing on addition and subtraction within 5 using visual supports like touch-points and pictures. Includes a collaborative partner game to reinforce skills through play.

Introduces strategies for balancing and solving one-, two-, and multi-step linear equations using inverse operations.

Focuses on mastery of integer operations, absolute value, and rational number properties through visual number line navigation.

A lesson focused on bridging the conceptual understanding of decimal division with the standard algorithm, covering three key scenarios: decimal by whole number, whole number by decimal, and decimal by decimal.

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.
