Description

Overview:
This lesson was used with a tier 3 fourth grade intervention math group to help students to progress from counting by tens and ones to combining and separating by tens and ones without skip counting. I used this Illustrative Math lesson, https://www.illustrativemathematics.org/content-standards/tasks/2106, and modified it to meet the students' needs. I modified the lesson by doing only the activities in Part 3 and then extending this by modeling the equations, that matched the hundreds chart work, with base ten blocks. I also made sure students saw the pattern in adding ones and adding tens and encouraged the proper place value terms. For example, "4 + 3 = 7 so 4 groups of ten + 3 groups of ten = 7 groups of ten which is the same as 40 + 30 = 70." I then extended this by having students add numbers with tens and ones to number with tens and ones with and without regrouping and asked them to first model it on the hundreds chart and with base ten blocks and then do the addition without skip counting (first adding the tens and then the ones and then combine the results).
