Second Grade Math Wall

I visited a wonderful second grade classroom last week!

Number bond, words and a place value chart for the number 152.

In the classroom, students were working on adding two-digit numbers. Some examples follow:

Adding 34 + 5:

Adding 24 + 32 on a place value chart
(from p. 29 of the Primary Mathematics Standard Edition 2A Textbook):

Decomposing addends to tens and ones to add 24 + 32:

A little harder to see…this student didn’t need to decompose the 24 and 32 into tens and ones, she just grouped the ones and the tens:

Next up, subtraction problems. Maybe with less circling/grouping of tens and ones.
