2nd Grade Math Unit 4

Big Idea:

Determine if a number up to 40 is even or odd, number that is 10 or 100 less/more up to 1,200, and unknowns in a word problem.

Student Expectations:

Focus TEKS

2.7(A) [Supporting] Determine whether a number up to 40 is even or odd using pairing of objects to represent the number

2.7(B) [Supporting] Use an understanding of place value to determine the number that is 10 or 100 more or less than a given number up to 1,200

2.7(C) [Supporting] Represent and solve addition and subtraction word problems where unknowns may be any one of the terms in the problem

Ongoing TEKS

2.2(D) [Readiness] use place value to compare and order whole numbers up to 1,200 using comparative language, numbers, and symbols (>, <, or =);

2.4(C) [Readiness] solve one-step and multi-step word problems involving addition and subtraction within 1,000 using a variety of strategies based on place value, including algorithms

Student Learning Targets:

• I will represent and compare whole numbers
• I will show even and odd using objects to 40.
• I will use an understanding of place value to determine the number that is 10 or 100 more/less than a given number up to 1,200.

Essential Questions:

• How can place value be used to compare numbers?
• How can number lines be used to make number comparisons?
• How can it be determined if a number is even or odd?
