This lesson was used with a tier 3 fourth grade intervention math group to help students move from counting by tens and ones separately to counting by tens in mid-decades (for example: 44 + 33, students would count 54, 64, 74, 75, 76, 77). I started this lesson by having students explore the columns of a hundreds chart. Students highlighted one column at a time and recited the counting sequence from top to bottom. We then connected the reciting to matching numeric equations. The next step was to use the counting by mid-decade knowledge to solve addition equations. Students used open number lines to model the addition.
