Using a base 10 number cube model, you will solve addition equations. You will decide how much of the second addend will be needed to get the first addend to the next round number. You will then add the remaining amount to get the final sum
A. Solve equations that add or subtract 1 or 10 with and without modeling with base-10 blocks
B. Model and solve addition equations that add a single-digit number to a two-digit number using a number line
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)
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)
