Learning Objectives
Students will be able to subtract from multiples of 100.
Introduction
(5 minutes)- Gather the students together in a comfortable area.
- Write 100 on the whiteboard. Ask students to turn and talk to an elbow partner, explaining what they see. Do not tell them the number orally prior to having them discuss with their partners.
- Allow a few students to share their ideas and record them on the whiteboard.
- Sketch a picture of a hundred block on the board using a square and show students the tangible hundred block.
- Explain to the students that today they will be learning about subtracting, or taking away, multiples of 100. Elaborate that multiples of 100 are numbers that can be produced, or made, by adding 100 to another number.
Beginning
- Write one hundred in a few languages and place it next to the number on the whiteboard (e.g. English, Spanish, student's home language, etc.)
- Encourage students to say the number they see in their home language (L1).
Intermediate
- Ask students to think-pair-share different objects they have seen in groups as large as one hundred. Examples may include: dollar bills, acorns, pennies, pencils at school, etc.
- Provide sentence frames for students, such as:
- I have seen one hundred ________ (objects) at ________ (place).
