Introduction

(4 minutes)
How Many Are There?Teach Background Knowledge TemplateWrite Student-Facing Language Objectives Reference
  • Prior to the lesson, write the following sentence frame on the board:
    • I think we should ________ because ________.
  • Create a strategy bank (like a word bank) on the whiteboard with phrases and visuals that represent the phrases: count by ones, skip count, use a number line, use my fingers, mental math, use blocks, hundreds chart, etc.
  • Begin the lesson by projecting a picture of a muffin pan filled with muffins (e.g 4 x 3 muffin pan). Explain that you are making an online order and need help figuring how many muffins are in the pan.
  • Ask students how you can figure out how many muffins there are in the pan. Say, "I'm not sure where to start. How can I figure out how muffins there are in the pan? Can you help me figure this problem out?"
  • Read through the strategies in the strategy bank, referring to the visuals to support student understanding. Next, read through the sentence frame and model choosing a strategy from the strategy bank to complete it.
  • Have students do a think-pair-share, using the sentence frame to explain what strategy they think you should use to figure out how many muffins are in the pan.
  • Explain to the students that many different strategies can be used to solve the problem. Today they will learn how to use skip counting, or counting forward using numbers other than one, and repeated addition, adding the same amount again and again, to figure out how many items there are in all!
