Prep work:
CORE ACTIVITIES DIVISION OF 100 Line up 100 ants in line formations so that each of the rows/columns has the same number of ants. Example using 20 ants: ant ant ant ant ant ant ant ant ant ant ant ant ant ant ant ant ant ant ant ant
READING FOR INFORMATION Read One Hundred Hungry Ants to discover any other formations the little ant suggested to move along more quickly. Compare your results with the story. DIVISION OF 100 Use the ant stamp to create a picture book of division facts based on the story. You may want to leave the answer blank for the reader to figure out. (ex. 100 ants = 25 ants in ___ rows.) Be very careful you stamp 100 ants in the correct formations so the reader can figure out the answer! Ask a friend or family member to read your book and figure out the answers. Sit with your friend so you can help when you =re needed.DIVISION OF 100 Using the line formations from the story, line up the plastic ants and then make up new verses to the song AThe Ants Go Marching One by One@ using the line formations you=ve made.
EXTENSION ACTIVITIES MONEY Put one plastic ant on each penny. Carefully put the correct number of pennies on each of the enlarged nickels. (ex. 5 ants/pennies on each nickel.). Tell someone what you discovered about the relationship between the pennies, nickels, and a dollar. Do the same thing with each type of enlarged coin. How many different ways can you make a dollar using all the same coins? Record your results on the How Many Ways to Make a Dollar sheet. MONEY GAME Gather your family together to play a money game. Starting with the youngest child, grab a handful of ants. Divide the ants into the following groups if possible: 25, 10, 5, and 1. Start with the largest number and work to the smallest number. Everyone can help with the grouping. Then trade the groups for coins that coincide with the number of ants. (For example, if there is a group of 25 ants, trade it for a quarter.) If each ant is worth one cent, how much is your handful worth? Record your amounts on the Handfuls game sheet. Example: Suzie grabs a handful of ants. She spreads them out on the table and discovers she can make a group of 25. Then she looks at the ants that are left in her handful and she can make a group of 10. She only has 3 left, so she makes three groups of 1. Then she trades her groups for a quarter, a dime, and three pennies. She =s still not real sure about the value of all the coins so she counts the ants to find her total which is 38 cents. Now it=s Dad=s turn, and Suzie can hardly wait to help!CALCULATOR PRACTICE Practice repeat subtraction to work on the division facts in the story. (ex. 100 -25-25-25-25=0) You can practice repeat addition to discover the multiplication facts in this story, too. (ex. 20+20+20+20+20= ___) BRAIN TEASER If the littlest ant did not return with the group, how many different ways could the 99 other ants form rows to get home? Use the plastic ants to find the answers. Use the 99 Tired Ants Function Chart to record your data. | |||||||||||||||||||
