Content Standard(s):
 Mathematics MA2019 (2019) Grade: K 10. Decompose numbers less than or equal to 10 into pairs of smaller numbers in more than one way, by using concrete objects or drawings, and record each decomposition by a drawing or equation. Example: 5 = 2 + 3 and 5 = 4 + 1 Unpacked Content Evidence Of Student Attainment:Students: Use objects or drawings to decompose the given number into at least two pairs of smaller numbers. Record their solutions using pictures or equations.Teacher Vocabulary:Decompose Equation Knowledge:Students know: "equal to" and the concept of equality meaning "the same as." Addition is putting together numbers and subtraction is taking apart numbers.Skills:Students are able to: Represent quantities physically, pictorially, and symbolically.Understanding:Students understand that: quantities may be named in a variety of ways. Diverse Learning Needs: Essential Skills:Learning Objectives: M.K.10.1: Identify plus, minus, and equal signs. M.K.10.2: Match numerals to objects or drawings. M.K.10.3: Identify numerals 1 to 10. M.K.10.4: Count 0 to 10. Prior Knowledge Skills:Notice same/different and some/all. Recognize numbers from one to ten. Subtract one from a set of objects (up to five objects). Add one to a set of objects (up to five objects). Given a group of objects (ten or less), divide the group into smaller groups in various ways. Given small groups of objects, create larger groups by combining the small groups. Take away objects from a large group to create two smaller groups. Put together two small groups of objects to create a larger group. Establish one-to-one correspondence between numbers and objects when given a picture a drawing or objects. Rote count to ten. Alabama Alternate Achievement Standards AAS Standard: M.AAS.K.8 Demonstrate an understanding of addition as "putting together" or subtraction as "taking from" in everyday activities, limited to 5 objects.
