By the end of October:

• Proficient with adding or subtracting 0,1, or 2 within 20

• Proficient with combinations that make 10 (ie: 8 + ___ = 10) and their related subtraction facts. (10 - 8 = ___)

By the end of December:

• Can represent whole number sums and differences within 100 on a number line (see addition and subtraction tab for examples)

By the end of January:

• Proficient with doubles (ie: 6+6, 7+7)

• Proficient with 10 and more facts and their related subtraction facts (ie: 10 + 7 = ___ and 17 - 10 = ___)

• Proficient in solving one step word problems within 100.

• Proficient in two digit addition and subtraction up to 100 using concrete models, drawings and strategies (see addition and subtraction tab for examples), up to four two digit numbers. (ex: 23 + 35 + 12)

• Proficient with estimating, chosing tools (ex: ruler, yard stick...), and measuring with customary units.

By the end of February:

• Can proficiently skip count by 5's, 10's, and 100's to 1,000.

• Can read, write, understand, and compare three digit numbers.

• Proficient in adding or subtracting 10 or 100 from 3-digit numbers (ex: 236 + 10 = ____  or  458 - 100 = _____)

By the end of April:

• Proficient in solving two step word problems within 100.
