3MA.B.2 use part-whole strategies to represent and solve real-life problems involving addition and subtraction with whole numbers within 10,000 (3.PAR.2)
2.b apply part-whole strategies, properties of operations and place value understanding, to solve problems involving addition and subtraction within 10,000; represent these problems using equations with a letter standing for the unknown quantity (e.g., 1,648 + n = 2,852); justify solutions using numerals, visual models, and/or words (3.PAR.2.2)
2.a add and subtract fluently within 1000 to solve real-life problems (3.PAR.2.1)
3MA.B.3 use part-whole strategies to solve real life mathematical problems involving multiplication and division with whole numbers within 100 (3.PAR.3)
3.g solve multi-step problems using multiplication and division involving whole numbers to 100; represent these problems using equations with a letter standing for the unknown quantity; justify solutions using numerals, visual models, and/or words (3.PAR.3.7)
3MA.D.5 solve real-life mathematical problems involving length, liquid volume, mass, and time and analyze graphical displays of data to answer relevant questions (3.MDR.5)
5.b tell and write time to the nearest minute and estimate time to the nearest 15 minutes (quarter hour) using an analog clock (3.MDR.5.2)
5.c solve meaningful problems involving elapsed time, including intervals of time to the hour, half hour, and quarter hour where the times presented are only on the hour, half hour, or quarter hour within a.m. or p.m. only (3.MDR.5.3)
5.g create real-life elapsed-time mathematical problems (Extension)

3MA.B.2 use part-whole strategies to represent and solve real-life problems involving addition and subtraction with whole numbers within 10,000 (3.PAR.2)
Use everyday math talk
Ask questions like:
“We have 2,350 points and need 3,000. How many more do we need?”
Practice part–whole thinking
Break numbers apart when adding or subtracting
(ex: 1,648 → 1,600 + 48).
Shopping math
Add prices of items or subtract change received.
Use equations with missing numbers
Write simple equations together:
1,648 + n = 2,852
Ask: “What number makes this true?”
Model thinking
Encourage children to explain how they solved a problem using:
Drawings
Number lines
Words
Expanded form
Daily fluency practice
Quick mental math games using numbers under 1,000 (adding scores, totals, or steps walked).
3MA.B.3 use part-whole strategies to solve real life mathematical problems involving multiplication and division with whole numbers within 100 (3.PAR.3)
Use real-life grouping
Ask questions like:
“If there are 4 plates and 6 cookies on each plate, how many cookies total?”
Share and divide
Divide snacks, toys, or teams equally and discuss remainders.
Multi-step problems
Example:
“We bought 5 packs of stickers with 8 stickers each. We gave away 10. How many are left?”
Write equations with unknowns
8 × n = 64
72 ÷ n = 9
Encourage explanations
Have children explain their answers using:
Drawings or arrays
Skip counting
Words
Equations
3MA.D.5 solve real-life mathematical problems involving length, liquid volume, mass, and time and analyze graphical displays of data to answer relevant questions (3.MDR.5)
Tell time daily
Practice reading analog clocks to the nearest minute.
Estimate time to the nearest 15 minutes (quarter hour).
Discuss elapsed time
Ask questions like:
“If dinner starts at 6:15 and ends at 7:00, how long did it last?”
Use real routines
Track time spent on homework, sports, or screen time.
Create time word problems
Encourage children to make up their own elapsed-time problems.
Measure together
Cook and measure ingredients.
Compare weights of grocery items.
Measure objects around the house.
Read simple graphs
Look at charts (weather, chores, screen time) and ask questions about the data.
