K. Unit 2 / Grade 1, Unit 1 ~
Odd or Even Sets
What Does This Look Like In:
K 1 2 3 4 5 A B
In this Kidspiration activity, students see the numbers 1-10 represented with
ten frames. First, students count the number of dots in each set, and type
in the correct number.

Series of ten frames representing different numbers, 1-10

 

Ten frames identified as the numbers 1-10, grouped into odd or even numbers
Students then decide which numbers are odd, which they have learned to mean
any set in which there is one object that cannot be paired. It is quite easy for the students to see that the odd numbers: 1, 3, 5, 7, 9 all have one dot that is not part
of a pair. Even numbered sets allow all of the dots to be paired.


Two collections of ten frames, one representing 21 and the other representing 24

To understand whether a two-digit number is odd or even, the same type of activity can be used (which can be downloaded below). The first number represents 21, which is clearly odd because one dot is not part of a pair. 24 is even because all of the dots are paired. Students can generalize that for any two-digit number, the ones place determines odd or even because all of the dots in a full ten frame are paired.

OT Teachers: This activity is shared as "oddeven10frame" in Handout-K-MATH and in T-share under MATH-K-Unit 2

Indictors:
6.K.3.1 recognize sets as having an odd or even number of elements.
6.1.3.1 identify odd and even numbers using objects.
