Operations and Algebraic Thinking, OA
• Represent and solve problems involving addition and subtraction
• Understand and apply properties of operations and the relationship between addition and subtraction
• Add and subtract within 20
• Work with addition and subtraction equations.
Number and Operations in Base Ten, NBT
• Extend the counting sequence
• Understand place value
• Use place value understanding and properties of operations to add and subtract

Measurement and Data, MD

• Measure lengths indirectly and by iterating length units
• Tell and write time
• Represent and interpret data

Geometry, G

• Reason with shapes and their attributes
 Mathematical Practices Make sense of problems and persevere in problem solving. Reason abstractly and quantitatively. Construct viable arguments and critique the reasoning of others. Model with mathematics. Use appropriate tools strategically. Attend to precision. Look for and make use of structure. Look for and express regularity in repeated reasoning.

## Year at a Glance

#### Trimester 3 (Mid-March - May)

 Youcubed Week of Inspirational Math Build Fluency within 10 Understand and apply properties of operations and the relationship between addition and subtraction. Work with addition and subtraction equations. Understand the equal sign. Add and Subtract to and within 20 -Represent & Solve Word Problems -Develop Strategies (count on, number lines, doubles, count back, making 10, missing addends/related facts, fact families) Represent & solve word problems with 2 and 3 addends (sums less than 20) Fact families with unknown in any position (number relationships) Organize, represent, and interpret data (w/ tally charts, picture graphs, and bar graphs) Set routines with counting collections, warm-ups, Number Talks, and Number Strings.   My Math: Ch 1, 2, 3, 4, 7 Count, Read, Write & Represent Numbers to 120 Understand Place Value -A “ten” is a bundle of 10 ones. -10 ones can regroup to make one ten. -Teen Numbers (count and write numbers 11-19) -30 is 3 tens and 0 ones Compare 2-Digit Numbers -Understand meaning of tens and ones digits -Compare using <, >, = Mentally Find Ten More/Ten Less of a 2-Digit Number Add & Subtract Tens Count on Tens & Ones Count Back by 10’s Add Tens & Ones with Regrouping Review Place Value Concepts as needed. Distinguish between defining vs. non-defining attributes. Compose 2D (chap.9) and 3D composite shapes.   My Math: Ch 5, 6. 9, 10 Review Place Value and Number Sense Concepts Measure lengths indirectly and by iterating length units. Fair Sharing - Chap.9 (partition circles and rectangles into halves and fourths) Tell and write time in hours and half-hours using analog and digital clocks.   My Math: Ch 8 and 9
