![]() ![]() ![]() Use a sheet of chart paper to record their findings. When all of the children are done, gather them and go over their recording sheets. ![]() They will start with the number one and work their way through to number 20. To begin, have the children take the number of bears that are on the recording sheet.For example, we already know that four is a(n)_ number.” (Even) “So you would write even next to the number 4.” Say: “You are going to put your findings on the blank space next to each number. Explain that, just like the children sorted the bears into even and odd groups, now they will work individually to sort bears and figure out which of the following numbers are even and which of the numbers are odd.Each child will receive 20 manipulatives, a sorting mat and a recording sheet with the numbers 1-20 on it.Step 3: Engage children in lesson activities. How many bears did I have before I gave them to Sally and Billy? (5) Do Sally and Billy each have an equal number of bears? (No) Can we pair each of Sally’s bears with Billy’s bears? (No) So is the number five an even or an odd number?” (Even) I am going to give one bear to Sally and one bear to Billy and one more bear to Sally and one more bear to Billy and one more bear to Sally. Counting as you hand out the items, say: “I have five bears in my hand. Using an odd number of manipluatives, give each child an item. Explain that, when there are an odd number of items, you and a friend cannot have an equal amount of that item (you cannot pair them up). Starting with the number one, count by twos. Explain that, when you START with the number one and count by twos, the numbers that you land on are odd. Any integer that CANNOT be divided exactly by two is an odd number. The last digit of an odd number will be 1, 3, 5, 7 or 9. Say: Odd numbers are the numbers that are not even.How many bears did I have BEFORE I gave them to Sally and Billy?” (Four) “Do Sally and Billy each have an equal (the same) number of bears?” (Yes) “So is four an even number or an odd number?” (Even) I am going to give one bear to Sally and one bear to Billy and another bear to Sally and another bear to Billy. Using an even number of manipluatives, give each child an item, counting as you hand out the items. Explain that, when there are an even number of items, you and a friend can each have an equal amount of that item (you can pair things up).ĭemonstrate: Ask for two volunteers. Count by twos up to 20 and explain that all of the numbers recited are even numbers. Even is a number that you land on when you count by twos. Introduce the concept of odd and even numbers. ![]()
