1st Grade Unit 5 At a Glance  (Parent Letter)

By the end of the unit students should be able to:

• I can add and subtract.

• I can use an equal sign to determine if equations involving addition & subtraction equations are true. (NC.1.OA.7)

• I can represent and solve addition and subtraction word problems with unknowns within 20 using objects and/or drawings. (NC.1.OA.1)

• I can model addition of a two-digit number plus a one digit number and a two-digit number plus a multiple of ten with concrete models, drawings, and/or number line and explain the reasoning used. (NC.1.NBT.4)

• I can use number lines, place value strategies, manipulatives or drawings, and addition/subtraction relationships to subtract a multiple of ten from any given decade number 10-90 (ex. 60-20=?). (NC.1.NBT.6)

• I can add numbers in any order in order to solve addition problems. (NC.1.OA.3)

• I can write an addition or subtraction equation, with an unknown representing one of the three whole numbers. (NC.1.OA.8)
