Section XI-9513 - Operations and Algebraic Thinking

A. Use manipulatives or representations to write simple addition or subtraction equations within 20 based upon a word problem.

B. Solve word problems within 20.

C. Using objects or pictures respond appropriately to "add __" and "take away ___."

D. Solve one step addition and subtraction word problems where the change or result is unknown (4 + _ = 7) or (4 + 3 = __), within 20 using objects, drawings, pictures.

E. Solve word problems that call for addition of two or three numbers whose sum is less than or equal to 20 by using objects t and drawings.

F. Recognize zero as an additive identity.

G. Use commutative properties to solve addition problems with sums up to 20 (e.g., 3 + 8 = 11 therefore 8 + 3 = __).

H. Use associative property to solve addition problems with sums up to 20.

I. Subtract within 20 by using the strategy of an unknown addend. For example, subtract 10 8 by finding the number that makes 10 when added to 8.

J. Decompose a set of up to 20 objects into a group; count the quantity in each group.

K. Count 2 sets to find sums up to 20.

L. Add and subtract within 20 supported by the use of manipulatives.

M. Identify and apply addition and equal signs.

N. Label simple equations as = or with the phrase "not equal."

O. Identify and apply addition, subtraction, and equal signs.

P. Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = [] 3, 6 + 6 = [].
