A focused assessment on skip counting by 2s within the range of 2-10. Students identify the missing number in a single sequence to demonstrate mastery of the pattern.

A primary math lesson focused on using a hundreds chart to solve two-digit addition problems, including those requiring regrouping by composing a ten. Students will learn to navigate the chart by jumping tens (moving down) and ones (moving right).

A 30-minute lesson teaching students how to use a 100's chart to add two-digit numbers, focusing on 2-digit + 1-digit with regrouping and 2-digit + multiples of 10. Students will learn the 'Jump and Slide' method for navigating the chart.

A culminating lesson where students apply their addition skills to solve summer camp word problems and mixed practice.

Students learn the standard algorithm for double-digit addition, focusing on correctly placing the 'carried' ten.

Students use expanded form to break down numbers and regroup sums, bridging the gap between drawings and the standard algorithm.

Students transition from physical blocks to drawing place value representations to solve addition problems with regrouping.

Students use base-ten blocks to model addition and practice 'trading' 10 ones for 1 ten to understand the foundation of regrouping.

A focused lesson on solving one-step addition and subtraction equations using a variety of number types including whole numbers, decimals, and fractions.

Identifying shapes, their attributes, and partitioning rectangles and circles into equal shares.

Focusing on addition and subtraction within 100, emphasizing word problems and mathematical language for operations.
