Grade 2 ~ Math Topic One: Understanding Addition and SubtractionTime Line: August 11 – August19, 2014
CCSSM:Operations and Algebraic Thinking2.OA.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.Number and Operation in Base Ten2.NBT.5. Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Mathematical Practices#7-Make sense of problems and preserve in solving them.
Learning Targets*I can choose when to use addition or subtraction in a word problem.*I can represent addition or subtraction word problems using objects, drawings, and equations with unknowns in all positions.*I can add and subtract numbers within 100 with ease by applying strategies (decomposing numbers into tens and ones, using commutative and associative properties) based on the numbers being added subtracted.
Vocabularypart, sum, addition sentence, whole, plus, add, addend, join, minus, separate, subtraction sentence, difference, subtract, fewer, more, related facts, equals, doubles, near doubles, number sentence.
Math Toolsnumber line, base-ten blocks, tens frame, hundreds chart, interactive hundreds chart, counters, cubes, part-part-whole (vertical), part-part-whole (horizontal) , addition flash cards, subtraction flash cards

Teacher Notes:
Use simple lunch bags or cutsie bags to
add these labels to and create a quick and easy math
game.Have kids add 10 cubes to
work on number pairs to 10. Have kids
add 20 cubes to work on
number pairs to 20. This game works best with partners as the
math talk is rich in content
about what they are doing and how they
know the answers.

I CAN add and subtract numbers
within 25 using
Math Fact Families to help me.
We learned how to write a subtraction fact
that is related to an addition fact.9
3 + 6 = 9
9 - 6 = 3
Today we’ll learn how to write all the related
addition and subtraction facts for a whole and two parts.
9 3 + 6 = 9
6 + 3 = 9
9 - 6 = 3
9 - 3 = 6
What do you call a group of people who
are related?
a famil
y
What are related facts?
Addition and Subtraction facts that have the same
numbers.
