Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between 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.

Lesson 1
Investigations
​U6, Inv. 1, Session 1.1 Story Problems with Stickers
 Student Activity U6, pg, 1, 2
Notes:
​You may recall Kim's ideas about starting out with a  Number Talk by putting up strips and singles and asking:  "How many stickers do you see?  How did you count them?"  Record the way they saw them with equations:  23 = 10 + 10 + 3    23 = 20 + 3     23 = 13 + 10
Next we discussed posing a word problem and representing the numbers on the whiteboard, then asking, "How can we solve this problem?"  Tip: Write the problem on the board.  Read it with the students.  Have them close their eyes and visualize it, then represent it with cubes, sticker strips and singles, or drawings of sticker strips and singles.
We also discussed eventually, in an upcoming lesson, connecting to the number line, especially with the strategy of keeping one number whole and then making jumps related to place value.

Math Expressions:
1) Student Activity Book (SAB), p. 73 - Write missing numbers on  101-200 chart
2) SAB, p. 74 - Extra practice with adding and subtracting within 20 word problems
3) Unrelated Challenge: Activity Card 2-1
4) SAB, p. 77 - Adding Tens or Ones
​5) Homework and Remembering, p. 45-46

Investigations
​U6 Inv.1, Session 1.2 More story problems with stickers 
Student Activity Book, pg. 4,5
​Student Activity Book, pg. 11 provides 2 problems for homework
Notes:
​This lesson connects the stickers and strips to the number line and the hundred chart, highlighting the strategy of keep one of the numbers whole and jumping by tens and ones.

Math Expressions Possibilities:
  1. SAB, p. 79 and 80 - Representing 3-digit numbers with place value drawings; Read and write number names
  2. Challenge Activity Card 2-3 - Make a List (AKA Number Riddles)
  3. SAB, p. 81 - Word Problems with Groups of Ten
  4. SAB, p. 82 - Adding One, Ten, or One Hundred
  5. On-Level Activity Card 2-4 - What's the Problem (reorder sentences to make a word problem)​ ​
Lesson 3
Investigations
U6, Inv.1, Session 1.3  Story Problems
Student Activity U6, pg. 7,8
This lesson is more practice solving sticker story problems using different models and strategies.

Math Expressions Possibilities:
SAB p. 83-84 - Comparing numbers based on place value.
Lesson 4
​U6 Inv. 1, Session 1.4 More story Problems
Student Activity U6, pg. 13,14
**Collect page 13 as an assessment.  Make time to analyze student work with your grade level team.**

Math Expressions Possibilities:
  1. SAB, p. 87-88 - Story problems with adding 2-digit numbers
  2. On-Level Activity Card 2-6 - Make a List (Target Problem)

Lesson 4
​U6 Inv. 2, Session 2.1 Guess my Number on the 100 chart
Resource master Unit 6 -M8
Student Activity book U6, pg. 16
  • Differentiation with playing with a 50 chart/ 200 chart  ( resource masters U6, M6 and M7)

Math Expressions Possibilities:
  1. SAB, p. 89 - 2-digit addition word problems (You will have to decide how you want to handle the directions which require a proof drawing and the partial sums method - probably tell students to ignore those directions and solve in a way that makes sense to them.)
  2. SAB, p. 90 - Two-step word problems (Model a visualize, discuss with a partner,  draw, then solve word problem protocol if you use these problems.) 
  3. On-Level Activity Card 2-7 - Scrambled Digits (You could modify this game to have students each draw 4 cards and each make a 2-digit plus 2-digit addition problem.  The student with the greatest sum wins all the cards.  You could also turn it into the smallest sum wins . . . or go for subtraction . . .)
