5-Group Finger Counting (3 minutes) Conduct activity as described in GK–M3–Lesson 1. Note: This activity helps to solidify students’ understanding of numbers to 10 in relationship to the five, which will be useful in upcoming lessons. Application Problem (5 minutes) Put the following sentence frame on the board, then read it to the students: I am taller than ______________. I am shorter than __________________. Draw two things on your paper that would make your sentence true. Tell your sentence to your partner. Does he agree that it is true? Note: Mentally comparing the height or length of two different objects to a third object provides a good cumulative review of the topic to date. This will help the students to be fully prepared for a more abstract development of measurement in upcoming lessons. Circulate during the activity to ensure that students are completing the sentence. Concept Development (29 minutes) Materials: (S) Bag of loose linking cubes per pair: 40 red and 15 of another color, or 30 of one color and 25 of another depending on how you build the stairs (the latter is pictured below), work mat (activity template) T: Do you remember the number stairs we made earlier this year? With your partner, make a set of red number stairs from 1 to 5. S: (Allow time to create stairs.) T: What did we do to make the rest of the stairs? S: We made a bunch of 5-sticks, then we put other cubes on top. T: You have great memories! Let's do that again. Use the rest of your red cubes (or orange cubes) to make as many 5-sticks as you can. Then add your other cubes to make the rest of your number stairs. Put them in order so you make sure you have them all.
