What We Are Learning Quarter 3
2MA.A.2 apply multiple part-whole strategies, properties of operations and place value understanding to solve real-life, mathematical problems involving addition and subtraction within 1000 (2.NR.2)
2.a add and subtract fluently within 20 using a variety of mental, part-whole strategies; by the end of grade two, know from memory all sums of two one-digit numbers (2.NR.2.1) (ongoing)
2.b find 10 more or 10 less than a given three-digit number and find 100 more or 100 less than a given three-digit number (2.NR.2.2)
2.c solve problems involving the addition and subtraction of two-digit numbers using part-whole strategies; add up to four two-digit numbers using strategies based on place value and properties of operations (2.NR.2.3)
2.d add and subtract fluently within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction (2.NR.2.4)
2.e use addition and subtraction within 100 to solve one- and two-step mathematical problems (involving all problem types) by using drawings and equations with a symbol for the unknown numbers to represent the problem
2MA.C.5 estimate and measure the lengths of objects and distance to solve problems found in real-life using standard units of measurement, including inches, feet, and yards and analyze graphical displays of data to answer relevant questions (2.MDR.5)
5.d ask questions and answer them based on gathered information, observations, and appropriate graphical displays to solve problems relevant to everyday life (2.MDR.5.4)

2.a Mental Math & Part–Whole Strategies Within 20 (2.NR.2.1)
2.a Mental Math & Part–Whole Strategies Within 20 (2.NR.2.1)
Practice “Think-It-Through” Math
Ask questions like:
“How can you make 10 first?” or “What do you know that helps you solve this?”
Use Everyday Moments
Count snacks, toys, or steps.
Practice quick facts during car rides or transitions.
Fact Fluency Games
Play card games, dice games, or online math games that focus on addition facts.
Encourage multiple strategies (doubles, near doubles, make 10).
2.b Find 10 or 100 More or Less (2.NR.2.2)
Number Talk at Home
Ask: “What is 10 more than 347?” or “What is 100 less than 582?”
Use a Number Chart
Show how moving up/down changes digits.
Real-Life Connections
Talk about money (10 more dollars, 100 more cents).
2.c Add & Subtract Two-Digit Numbers Using Place Value (2.NR.2.3)
Break Numbers Apart
Example: 47 + 35 → (40 + 30) + (7 + 5)
Use Household Objects
Group items by tens and ones.
Add Multiple Numbers
Add prices, scores, or distances together.
Discuss Strategies
Encourage children to explain why their strategy works.
2.d Fluency Within 100 Using Flexible Strategies (2.NR.2.4)
Use Friendly Numbers
Example: 58 + 7 → add 2 to make 60, then add 5.
Connect Addition & Subtraction
Show how subtraction can “undo” addition.
Mental Math Challenges
Ask children to solve without paper and explain their thinking.
2.e Solve One- and Two-Step Word Problems (2.NR.2.5)
Turn Daily Life into Word Problems
Shopping, cooking, sports, or chores.
Draw It Out
Encourage drawings or number models to show thinking.
Use Equations
Write equations with a missing number (☐ + 25 = 68).
Ask “What’s Happening?”
Help children decide whether to add or subtract and why.
2MA.C.5 – Measurement & Data (2.MDR.5)
2MA.C.5 – Measurement & Data (2.MDR.5)
Estimating & Measuring Length (2.MDR.5)
Estimating & Measuring Length (2.MDR.5)
Estimate First, Measure Next
Ask: “About how long do you think this is?”
Use Standard Tools
Measure with rulers, tape measures, or yardsticks.
Compare Lengths
Order objects from shortest to longest.
Real-Life Uses
Measure furniture, height, or distance walked.
5.d Asking & Answering Questions Using Graphs (2.MDR.5.4)
Collect Family Data
Track daily steps, weather, screen time, or favorite snacks.
Create Graphs
Use bar graphs or picture graphs.
Ask Meaningful Questions
“Which is the longest?”
“How many more?”
“What do you notice?”
Solve Problems Using the Graph
Encourage children to explain answers using the data.
