1. A Grade-by-Grade Progression of “A Story of Units”
Common Core
Part 1 of 2 (Grades K – 2)

2. Plan:
Step through “A Story of Units” grade-by-grade K-2

3. Overview Chart

4. Pre-Kindergarten Well-planned math program Count to 5 with meaning
Explore the definitions of circle, rectangles, etc.
“How many” up to 10 using familiarity with 5

5. Pre-Kindergarten Comparisons: small, big, large, tall, etc.
Fluency with meaning of numbers 1-10, counting numbers 1-20.
No timeline as of yet on when it will be started/completed

6. Kindergarten Module 1: Numbers to 10 Module 2: 2-D and 3-D Shapes
Module 3: Comparison of Length, Weight and Capacity and Numbers to 10
Module 4:Number Pairs, Add and Subtract to 10
Modules 5: Numbers 10-20, Count to 100
Module 6: Analyzing, Comparing and Composing Shapes

7. Connection to the Emphases?

8. Kindergarten Same themes as Pre-K Numbers 1-10 with “1 more, 1 less”
Comparisons: taller than, shorter than, longer than, heavier than—leading to…

9. Kindergarten More than, less than:
7 is 2 more than 5
7 is 2 less than 9
1 more, 2 more, 3 more than
Comparing numbers leads to number bonds: (Decomposing and Recomposing Numbers)
3 is less than and 4 make 7.
Number bonds lead to addition/subtraction 7 3 4

10. First Grade: Module 1: Sums and Differences to 10
Module 2: Intro to Place Value (Add, Subtract within 20)
Module 3: Order, Compare Lengths as Numbers
Module 4: Place Value, Comparison, Add and Subtract to 40
Module 5: Identify, Compose and Partition Shapes
Module 6: Place Value, Comparison, Add and Subtract to 100

11. Connection to the Emphasis?

12. First Grade
Fluency with add/subtract facts begins right away and continues the entire year
Main strategy for adding/subtracting across a 10: “make 10” This strategy begins the realization of…
8 + 5 = 8 + (2 + 3) = (8 + 2) + 3 = = 13

13. First Grade
A major concept goal for first grade: Group “10 ones” as a single unit: 1 ten
Module 3 on length provides a few weeks to practice “making a ten” and also allows for a wider variety of word problems
“Add within 40” module establishes 1 ten

14. First Grade
“Add within 100” module begins model work with addition and subtraction of two 2-digit numbers
In between these two heavy-duty number modules is a module on shapes

15. Second Grade: Module 1: Sums and Differences to 20
Module 2: Add, Subtract Length Units
Module 3: Place Value, Counting and Comparison to 1000
Module 4: Add and Subtract within 200 and Word Problems to 100
Module 5: Add and Subtract within 1000 and Word Problems to 100
Module 6: Foundations of Mult. And Division
Module 7: Problem Solving with Length, Money and Data
Module 8: Times, Shapes, and Fractions as Equal Parts of Shapes

16. Connection to the Emphasis?

17. Second Grade
The first module on “numbers to 20” is the beginning of a yearlong fluency program on numbers and time
The second module on measurement plays a key role in grade 2: it establishes the meaning of the term “unit.”
Place value units are the study of the third module. In particular, …

18. Second Grade Place value units are the basis of the algorithms 1 2 6 7
7 ones + 6 ones = 13 ones = 1 ten 3 ones
1 ten + 6 tens + 2 tens = 9 tens 1
2 6 7
+ 2 6
2 9 3

19. Second Grade
1 apple, 2 apples, 3 apples, ten, 2 tens, 3 tens, … leads to 1 three, 2 threes, 3 threes, …
4 threes = 12 ones

20. Second Grade Last 2 modules end with:
Problem solving with length, money and data
Money: dollars, dimes, pennies (and nickels and quarters)
Analog clocks (curved number line)
Simple fractions as equal parts of shapes and clocks/time
