A formative assessment lesson focused on adding up to four two-digit numbers using various place value and operational strategies.

A K-2 math lesson focusing on solving addition and subtraction word problems using part-part-whole mats, bar models, and number lines, while applying counting on/back and making-a-ten strategies.

This lesson introduces addition within 20 through the 'Make Ten' strategy and Number Bonds. Students progress from using physical counters to visual ten frames and finally to abstract equations.

A focused lesson on 3-digit subtraction where students practice regrouping from the tens place to the ones place. includes a visual-heavy worksheet and an answer key.

A comprehensive introduction to 3D geometric shapes including cubes, spheres, rectangular prisms, cones, pyramids, and cylinders. Students will learn to identify these shapes, count their attributes (faces, edges, vertices), and find them in the real world.

A comprehensive math review lesson designed to reinforce key elementary math skills including logical ordering, 2-digit subtraction, geometric attributes, and equal parts/fractions. This lesson uses a repeated "at-bat" structure to build mastery through multiple variations of the same problem format.

A cumulative review and formal assessment of perimeter and area concepts in a shortened Friday block.

Reinforcing the concept of area through counting squares in arrays and understanding the relationship between rows, columns, and total area.

Introduction to area by partitioning rectangles into equal-sized rows and columns. Students will visualize area as the total number of squares inside a boundary.

Advanced perimeter practice including finding missing side lengths and solving real-world word problems involving fences and borders.
