Week 2
2nd Grade → 3rd Grade · Addition within 100 and R controlled
Math
Addition Within 100
Adding two-digit numbers where the ones do not carry — 34 + 25. Early second grade.
The mistake to watch for. Misaligning the columns when copying from a horizontal problem, so 34 + 5 becomes 34 + 50.
How to help. Use graph paper or turn lined paper sideways. One digit per box keeps the columns honest.
A worked example
Try 34 + 25. Add the tens: 30 + 20 = 50. Add the ones: 4 + 5 = 9. Put them together: 50 + 9 = 59.
Reading & language
R-Controlled Vowels
Recognizing that a vowel followed by r doesn't make its usual short or long sound — the ar in car, the ir in bird. Second grade, often taught right alongside vowel teams.
The mistake to watch for. Sounding out the vowel on its own first, then adding the r as an afterthought — turning "car" into "ca-er".
How to help. Same approach as vowel teams: practice ar, er, ir, or, and ur as single sound units before reading them inside full words.
A worked example
In 'bird', the r changes the vowel sound. The letters 'ir' make the /ur/ sound — the same sound as 'er' in 'fern' and 'ur' in 'turn'.
