As we wrap up measurement, we will head into unit 5, covering addition and subtraction. We will learn about:
How to represent addition and subtraction with objects, fingers, equations, and mental math
Solve addition and subtraction word problems to add and subtract within 10 (using objects or pictures to show). In Kindergarten, all of the problems are still read out loud, students are not expected to be able to read a word problem independently until 2nd grade.
Decompose numbers less than or equal to 10 into pairs in more than 1 way. For example, separate 5 into 2 groups in more than one way (1+4 or 2+3 or 0+5).
For numbers 1 to 9, find the number that makes 10 when added together, using objects, pictures, or equations (6 and 4 more makes 10, 5 and 5 makes 10, 7 and 3 more makes 10).
Fluently add and subtract within 5- students may NOT use fingers, objects, or pictures. This should be purely mental math.
