Grade 2: Even and Odd Numbers
A number is even if it can be split into pairs with none left over, and odd if there is always one left alone. Use the tool below to build a number out of dots and see whether they pair up perfectly.
What Are Even and Odd Numbers?
Imagine giving each dot a partner. If every dot has a partner, the number is even. If one dot is left without a partner, the number is odd. Even numbers can be shared equally between two people; odd numbers cannot.
Use the buttons to change the number and watch the dots pair up.
