You will be adding single digit numbers to two digit numbers in this activity. You will be allowed to use a number line to assist with these addition equations
A. Solve equations that add or subtract 1 or 10 with and without modeling with base-10 blocks
C. Solve equations that add a single-digit number to a two-digit number (Part 1)
D. Choose matching addition expression and sum
E. Determine a missing addend to add up to the next round number with and without a model of base-10 blocks
F. Determine a missing addend to add up to the next round number and solve the equation (Part 1)
G. Determine a missing addend to add up to the next round number and solve the equation (Part 2)
H. Determine a missing addend to add up to the next round number and solve the equation (Part 3)
I. Model and solve 2-digit addition equations with exchanging using base-10 blocks
J. Solve addition equations across 10 using a number line
K. Solve addition equations across a 10 by splitting an addend to make a ten
L. Solve equations that add a single-digit number to a two-digit number (Part 2)
