Students learn to mentally subtract 10 and 100 from 3-digit numbers, observing which digits change and which stay the same.
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.
Introduction to perimeter as the distance around a shape. Students will learn to measure sides and add them together to find the total perimeter.
A math lesson focused on identifying the correct operation (addition, subtraction, multiplication, or division) to solve arcade-themed word problems using double-digit numbers without regrouping.
A comprehensive word problem review focusing on addition and subtraction within 200, featuring repetitive practice (at-bats) to build fluency and mastery.
A math review packet focusing on basic addition, subtraction, number combinations, and visual representation of groups, including a student worksheet and an answer key.
A foundational lesson on 3-digit addition focusing on composing (regrouping) across exactly one place value (either the ones or the tens). Students use a blueprint-themed packet to practice their architectural precision in mathematics.
A foundation-level lesson introducing multiplication as equal groups, focusing on the numbers 2 and 10 through visual aids and hands-on flashcard practice.
A focused lesson on identifying missing addends within 20 using number bond visual representations to build algebraic thinking and fluency.
A magical math lesson where students count, sort, and graph different types of ponies to practice data representation and comparison skills.
A high-energy math expedition where students master time, money, shapes, and fractions through a jungle-themed safari adventure. This lesson includes interactive slides, a comprehensive teacher guide, and skill-specific practice pages.
A mini-lesson for second graders on telling time to the nearest five minutes, including the concepts of AM and PM, featuring a whimsical 'Time Traveler' theme.
A hands-on introduction to fractions (halves, thirds, and fourths) using a bakery theme. Students will identify equal parts and sort shapes based on their fractional divisions.
