1st Grade Math Unit 2

Big Idea:

Problem solving with addition using different strategies

Student Expectations:

Priority TEKS

1.3B [Supporting] Use objects & pictorial models to solve word problems involving joining, separating, and comparing sets within 20 & unknowns as any one of the terms in the problem such as 2+4=__, 3+7=__, and 5= __-3

1.3D [Supporting] Apply basic fact strategies to add & subtract within 20, including making 10 and decomposing a number leading to 10;

1.3E [Supporting] Explain strategies used to solve addition & subtraction problems up to 20 using spoken words, objects, pictorial models, and number sentences;

1.5D [Readiness] Represent word problems involving addition & subtraction of whole numbers up to 20 using concrete & pictorial models & number sentences

Ongoing TEKS

1.2(A-C)Number and Operations - The student applies mathematical process standards to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system related to place value. The student is expected to: (A) recognize instantly the quantity of structured arrangements; (B) use concrete and pictorial models to compose and decompose numbers up to 120 in more than one way as so many hundreds, so many tens, and so many ones; (C) use objects, pictures, and expanded and standard forms to represent numbers up to 120.

Student Learning Targets:

• I will identify the difference between parts and whole in an addition equation
• I will solve addition problems to 20 using manipulatives and pictures
• I will use different strategies to solve the same problem
• I will write a story problem

Essential Questions:

• What is the relationship between the parts and a whole?
• How would you solve for an unknown number?
• How can we solve the same problem in more than one way?
