A cumulative review and performance assessment where students solve 5 oral or pictorial problems to 30, demonstrating mastery of the unit's goals.

Combining skills to determine the correct operation (+/-) for oral and pictorial problems, writing the number sentence, and solving using a number line.

Focusing on subtraction within 30 using number lines and a monster truck theme. Students will practice 'reversing' or 'crushing' numbers by moving backward on the number line.

Focusing on addition within 30 using number lines and a Lego building theme. Students will practice 'building up' their totals by hopping forward on the number line.

A review of math vocabulary for addition and subtraction using a Golden State Warriors theme. Students will learn to identify keywords in oral problems to determine whether to add or subtract.

A final project-based assessment where students demonstrate their ability to build arrays, identify even/odd groups, and write repeated addition equations.

Students practice skip counting by 2s, 5s, and 10s as a fast-track method for counting large groups of building supplies.

Students explore even and odd numbers by pairing objects and building 'towers of two' to see if any blocks are left over.

Students build and analyze rectangular arrays (up to 5x5) using building blocks, connecting the rows and columns to repeated addition.

Students use manipulatives to create equal groups and write repeated addition equations to find the total, laying the conceptual groundwork for multiplication.

A lesson focused on mastering 3-digit subtraction with regrouping through detective-themed problems and conceptual explanations. Students will learn to explain why regrouping works using place value.

A comprehensive 2nd-grade lesson on 3-digit addition using place value strategies and base-ten models. Students will learn to add hundreds, tens, and ones, including composing new tens and hundreds.

A visual-heavy lesson using a pixel-art theme to help 2nd grade students understand place value up to 100, expanded form, and the relationship between ones, tens, and hundreds using 100-grids.

A final cumulative review and performance assessment where students demonstrate mastery of operation choice and number line subtraction to earn their championship trophy.

Students practice subtraction math sentences up to 30 using number lines, themed around the Golden State Warriors and Monster Truck racing.

Students review addition and subtraction vocabulary and learn to determine the correct operation for word problems within 20, featuring Lego and Monster Truck themes.
