• 1. Math, Measurement, and Photography A lesson for Kindergarten By: Jessica McCord ECE 4401/01
• 2. Ms. McCord decided to go to store to buy items for the classroom. She started with alphabet cards. Each card is 3 paperclips long. If one card is taken away, how many paperclips will be left?
• 3. Hint for Problem #1 There are 6 paperclips altogether. 3 of them will go leave when one card is taken away. *BONUS* What sight word does this spell?
• 4. Ms. McCord also bought a pack of colored pencils. One colored pencil is 6 paperclips long. How many times will 2 paperclips go into 6 paperclips?
• 5. Hint for Problem #2 Count by 2’s until you get to the number 6. How many times did you count by 2’s until you got to 6?
• 6. Ms. McCord could not bring herself to leave the store without buying some books. If 1 book is 5 paperclips long, how many paperclips would we use to measure 2 books?
• 7. Hint for Problem #3 Both books are the same size. If 1 book is 5 paperclips long, then the other book must also be 5 paperclips long.
• 8. Ms. McCord decided that two books just weren’t enough. She decided to buy one more book at the store. This book is 10 paperclips long. How many groups of 5 can you take out of the 10 paperclips?
• 9. Hint for Problem #4 Subtract 5 paperclips from the 10 paperclips until you get to 0. How many times did you have to do that?
• 10. Answers Problem #1: 3 paperclips left Problem #2: 3 times Problem #3: 10 paperclips Problem #4: 2 times
• 11. GPS MKM1. Students will group objects according to common properties such as longer/shorter, more/less, taller/shorter, and heavier/lighter. a. Compare and order objects on the basis of length. MKP2. Students will reason and evaluate mathematical arguments. a. Recognize reasoning and proof as fundamental aspects of mathematics. MKN2. Students will use representations to model addition and subtraction. a. Use counting strategies to find out how many items are in two sets when they are combined, separated, or compared.
