Common Core StandardsRepresent and solve problems involving addition and subtraction.
Represent and solve problems involving addition and subtraction.
CCSS.MATH.CONTENT.2.OA.A.1

Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

Use place value understanding and properties of operations to add and subtract.

CCSS.MATH.CONTENT.2.NBT.B.5
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

Lesson 2 
​
(2-Day Open-Response Task/Performance Task)
​

Day 1:  Understand the problem and solve.

Day 2: Look at student work samples.  "What do you notice about how ____ organized her work?  What do you understand from looking at her work?  What new ideas do you have about improving your work?"  Have students spend a large chunk of time revising their work.
*Get together as a 2nd grade team to analyze student work.*

Focus Common Core Math Practices:
Make sense of problems and persevere in solving them.
Look for and make use of structure. (organizing your work and noticing patterns)

Task:
The sum of two numbers is 20.  What might the two numbers be?  Show all the different possible solutions.

Questions to Ask Students:
What do you know?
What do you need to find out?
What tools might help you solve this problem?
How will you organize your work?






Lesson 3
U6, Session 2.4 Sticker Books 

Student Activity Book U6, pg. 27, 28

Students work with a visual model (10 x 10 grid) of numbers to represent and add 2-digit numbers.  They also connect the grid model to the number line.

Math Expressions Possibilities:
  1. On Level Activity Card 2-9 - Make 100
