Tell Me – Show Me/ Compare Number Name, Place Value, & Expanded Form Materials: Place Value Blocks Directions: Variation-Tell Me: Partner A shows unit squares to Partner B and asks, “How many do you see?” Partner B tells Partner A the amount. Then, Partner A selects a unit and adds it to the existing amount. Partner A asks Partner B: “How many do you see?” “What is the place-value name of this number?” “What is the standards base-ten name of this number?” Partner B tells Partner A the amounts. Partner A asks Partner B: “Show me 3 different ways to make this same amount.” Partner B makes the 3 different ways and tells Partner A each amount in various ways. Last, Partner A asks Partner B to write the amount on a piece of paper. Then, reverse roles and repeat. Variation- Show Me: Partner A asks Partner B, “Use the blocks to show me (a 2 or 3-digit number).” Partner B uses the blocks to create the number given. Partner A asks Partner B, “Now show me the number in a different way”. Reverse roles and repeat. Variation A- Compare: Partner A names two decimal numbers and asks Partner B to show both numbers on the place value mat. Then, Partner B compares the numbers and describes the relationship between them. Reverse roles and repeat. Variation B- Compare: Partner A names three numbers and asks Partner B to show the 3 decimal numbers and order them from greatest to least. Human Number Line Materials: 2 sets (different colors) 12 large digit cards (0, 0, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and 1-2 cards with commas, sticky notes (or scraps of paper), 2 timers Directions: Randomly distribute the digit cards to the class. Call out a number and have the students line up in a straight line beside one another and hold up their number card for everyone in the room to see. Ask the class if everyone agrees if the number formed is, indeed, the correct number. If it is incorrect, have the students tell directions to the standing students where to move in order for the number to be correct. Once the number formed is correct, have each student tell the value of their digit and return to their seat. Continue multiple times. Variation: Create two opposing teams (using 2 sets of cards). Have each team select a time-keeper and an auctioneer (number-caller). Have each team member write one number (up to one million) on a sticky note and then give all of the written numbers to the opposing team’s auctioneer (be sure that each team has the same amount of numbers to call). Provide each time-keeper with a timer, and have them set the timer for a given amount of time (ex. 4 minutes). On your mark, have each team’s auctioneer call out a number for their team to quickly make, state the value of each number, and sit back down before another number is called. At the end of the 4 minutes, the team who made the most numbers correctly wins. Race for a Square Materials: Place Value Blocks, place-value mat Directions: With your partner, take turns rolling one die. Each player rolls a die, places that many unit squares on his or her place value mat, and makes all possible trades. The game continues until one player has enough to make a square = 100. Make a Square Disappear Materials: Place Value Blocks, place-value mat Directions: Each partner needs a place value mat with a square (=100) placed on it. With your partner, take turns rolling one die. Each player rolls a number, takes that many unit squares on his or her place value mat away, and makes all possible trades. The game continues until one player has removed all unit squares. Close to 100! With your partner, take turns rolling one die. For each roll, place the number rolled in one of the 4 spaces on the Close to 100! Sheet, deciding which location would be most beneficial for reaching a total of 100. After four rolls, add the numbers together and record the sum in the blank. Determine the score for that round by figuring out the difference between the sum of the two numbers and 100. At the end of five rounds, each player totals the score. The lowest score wins.
