Unit Title
NRS Level	Level 2
Length of Lesson	60 minutes

To introduce fractions in order for students to build on prior knowledge and expand toward calculation with them

At the end of this lesson, students will be able to:

· Solve word problems in varied contexts using a letter to represent the unknown.

“I can apply calculation to solving word problems.”

3.NBT.2
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
3.NBT.3
Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 x 80, 5 x 60) using strategies based on place value and properties of operations.

3.NBT.1
Use place value understanding to round whole numbers to the nearest 10 or 100.
3.OA.7
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 x 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
3.OA.8
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
