1st Grade Math Unit 5

Big Idea:

Ten is a friendly number that applies to many math strategies

Student Expectations:

Priority TEKS

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;

Focus TEKS

1.2A [Supporting] Recognize instantly the quantity of structured arrangements

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.

1.3D [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;

Student Learning Targets:

• I will represent numbers on a 10 Frame
• I will count ten frames by using 5 and 10 as a benchmark
• I will find the missing part of 10 when a whole or part is known
• I will write numbers in different ways

Essential Questions:

• How can making ten help us solve other math problems?
• How can numbers be arranged in different ways?
