Odd and even

Build strong number sense through pattern recognition. Learners investigate whether the sum of each problem will be odd or even if they add certain combinations of numbers together. They complete 12 problems, adding odd+odd, odd+even, or...

There are multiple objectives at play here as scholars solve addition and subtraction problems and determine whether the sums and differences are odd or even. As they solve these, encourage pupils to observe patterns. What happens when...

Get in the Valentine's Day spirit with an addition activity. Scholars solve problems and color answers different colors depending on whether they are even or odd.   

In this odd and even bubbles worksheet, 2nd graders evaluate 20 numbers as being even or odd, then color the odd and even numbered bubbles according to the color key given.

A great way to show the difference between odd and even numbers is by using blocks. The graphics in this PowerPoint do a great job at showing the two groups of numbers. Tip: After viewing this presentation, have students experiment with...

What's odd? What's even? And what is the pattern? Learners explore addition problems to answer this question, deciding if the answer to each equation is odd or even. They then draw a two-column table to illustrate the outcomes of the...

Building on the previous lesson in this series, young mathematicians develop a deeper understanding of the alternating pattern with even and odd numbers. Pictures and number lines guide learners as they observe how the observed pattern...

Teach young mathematicians that all even numbers can be written as the sum of two equal addends with the third video in this series. This fact is clearly demonstrated with multiple examples, using number lines and visual models to...

Here's a good worksheet to use as a way to assess how well the class understood the lesson on odd and even number. They will mark odd and even numbers, add odd number, add even numbers, mark the odds and evens, then answer 3 related fill...

Nobody wants to be the odd man out. The first video in this series uses prior knowledge about making fair teams to teach young mathematicians about even and odd numbers. Pictures and number lines offer support as children learn that even...
