Use grouping strategies to determine if a given quantity is even or odd.
Classify numbers as even or odd.
Understand that even numbers can be divided into two equal groups and odd numbers cannot be divided equally into two groups.
Recognize that even numbers have a 0, 2, 4, 6, or 8 in the ones’ place.
Recognize that odd numbers have a 1, 3, 5, 7, or 9 in the ones’ place.
Odd, Even, Pairs
- Students determined if the quantity of the number given were odd or even by matching pictures in pairs. If it can be matched in pairs, it is even if not it is odd number.
- Using a hundreds chart, students were to identify the odd and even by coloring it in 2 diffent colors.
- Students rolled the dice. Count out that number of objects for each cloud or bubble. They wrote the equation to show that an even number is a sum of two equal addends, whether its an odd or even number.
Work with equal groups of numbers to gain foundations for multiplication (repeated addition).
Write an addition equation to express the sum of equal addends.
Set the foundation for later exploration of multiplication (i.e. 2+2+2+2 =? How many 2s did you add? When you add 4 number 2s together, what do you get?)
- Students wrote the given number to add a white board using the correct symbol for addition number sentence.
- Students drew pictures to represent each number then add it all together.
