CCSS.MATH.CONTENT.1.NBT.B.2.A

10 can be thought of as a bundle of ten ones — called a "ten."

CCSS.MATH.CONTENT.1.NBT.B.2.B

The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.

CCSS.MATH.CONTENT.1.NBT.B.2.C

The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

Summary: A fun book for children to learn how to count to 100. At first there are 100 mice, then 100 cats, then 100 moles, then 100 sheep, then 100 birds, then 100 fish, then 100 elephants, then 100 kids, then 100 ants, then 100 cars and trucks, and finally 100 houses. Readers are to count each animal, person, and item and are prompt to find specific details within the images, such as “How many different kinds of fish are there” and “How many ants are carrying candy?” At the end, readers are encouraged to count 10 of each animal, 10 kids, and 10 houses to make 100 in all.

Classroom Ideas/Lesson Ideas:

Students will bridge prior knowledge with new learning by the teacher asking questions that previews the upcoming topic- such as, "Have you ever thought why grouping ten things together is so important?" and then, "What might happen if you tried to count all things in a group one at a time?"

*After students provide their feedback, the teacher will explain to students that it is quicker and easier to count things bundled up.

*Students will be told that they will now play a game called "Making Bundles".

*Students will be handed the lesson's materials:

·         Craft Sticks

·         Mat

·         Die (0-6)

*Students will be instructed to roll a die and place that number of sticks on their mat.

*Students will be instructed to keep rolling the die and adding sticks to their mat until they have enough to make 10 bundles of ten like the animals/kids/items in the story book to make 100 in all.
