Big Idea:

Addition and subtraction strategies to 12

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;

1.3C [Supporting] Compose 10 with two or more addends with and without concrete objects;

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;

Focus TEKS

1.3F [Readiness] Generate & solve problem situations when given a number sentence involving addition or subtraction of numbers within 20;

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.

1.3C [Supporting] Compose 10 with two or more addends with and without concrete objects;
