1st Grade Math Unit 8

Big Idea:

Skip counting makes counting sets more efficient

Student Expectations:

Priority TEKS

1.5B [Supporting] Skip count by twos, fives, and tens to determine the total number of objects up to 120 in a set;

Focus TEKS

1.5A [Supporting] Recite numbers forward & backward from any given number between 1 and 120;

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;

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 count the same set of objects using different skip counting patterns.
• I will write about how and why I skip counted.

Essential Questions:

• How can we making counting easier.
