Students have more practice solving addition equations with exchanging. They split an addend by using a number bond to find the amount that makes the next ten, and a remainder. Then add the tens number and remaining ones to solve
A. Use base-10 models to add ones to a 2-digit number
B. Add ones to a 2-digit number
C. Use base-10 blocks to add a tens to a 2-digit number
D. Solve addition equations adding tens or ones to a 2-digit number
E. Identify tens numbers from a set
F. Given a number along a number line, identify the next ten
G. Identify the next ten from a given number, without models
H. Use base-10 blocks to practice adding to make a next ten
I. Identify the next ten and find the missing addend
J. Find the missing addend to make the next ten from a given number
K. Use base-10 blocks to solve addition equations with exchanging
L. Use number bonds to solve addition equations with exchanging (Level 1)
N. Solve addition equations with exchanging, using a number bond if needed
O. Add ones to a 2-digit number
P. Add ones to a 2-digit number, with and without exchanging
