190 Top-It Card Games Objective To introduce a game that reinforces number recognition and number comparisons. Whole Group Small Group Partners Center Key Concepts and Skills • Read numbers. [Number and Numeration Goal 3] • Compare numbers. [Number and Numeration Goal 6] Terms to Use more, less, higher, lower Materials Home Link Master (Math Masters, p. 32); card decks made from two sets of Small Number Cards 0–20 (Math Masters, pp. 105–107) or the cardstock number cards in the My First Math Books. A Core Activities ► Playing Top-It (Math Masters, pp. 105–107) Show children the card decks and explain that each deck has two of each of the numbers 0–20. Pick two cards from a deck. Have children say the numbers and tell you which number is more and which is less. Ask children to share how they knew which number was higher. (If children don’t share them, model strategies such as checking the number line or counting out loud.) Repeat this warm-up activity a few times before teaching how to play Top It. (You may remember the game as War.) Give each pair of children a shuffled card deck. Direct them to divide the deck so that each child has the same number of cards. Have them place their stacks facedown on the table or desk, turn over the top card, and read the numbers. The player with the larger number takes both cards. If players have the same number, they turn over and compare the next card on their stacks until someone wins the round and takes all the cards. 188-221_EMCS_T_GK_TGA_U04_57511X.indd 190 Planning Tip Use two copies of Math Masters, pages 105–107, cut and laminated or mounted on cardstock to prepare each card deck. (Alternately, combine sets of the cardstock number cards in the My First Math Books.) You may want to combine some of the decks you made for Activity 3-9. Each pair of children will need a deck of cards, so you may want to teach the game in small groups. Adjusting the Activity Provide counters or cards with dots and numerals for children who may still need concrete or visual supports to compare numbers. Some children may also benefit from using only numbers 0–10 at first. AUDITORY KINESTHETIC TACTILE VISUAL 1/25/11 12:33 PM The winner is the player with the most cards when play stops. Below are variations of Top-It that you can introduce as children are ready. Opposite Top-It (or Bottom-It) The smaller number takes the cards. Top-It with a Spinner Prepare a spinner with sections labeled “Larger” and Name Top-It Family Note Top-It reinforces number recognition and helps children learn to compare two numbers to decide which one is greater or less. (You may remember this game as War.) 䉬 “Smaller.” Players spin before each round to decide which number takes the cards. Number cards from school or a deck of cards Players 2 Skill Compare numbers Directions 1. Shuffle a deck of cards and then divide it between two players, turning the cards facedown on the table. 2. Players turn over their top cards and read the numbers aloud. 3. The player with the greater number keeps both cards. If both players get the same number, they turn over the next card on their stacks until one player wins and takes all the cards for that round. Play Top-It with someone in your family.

Children can play a computer version of Top-It using Everyday Mathematics EM Games. Date 42 HOME LINK (Math Masters, p. 32) Children teach a family member how to play Top-It. ► Skip Counting by 10s (Revisit Activities 1 12 and 3 15, pp. 68 and 170) Play Give the Next Number, but have children count by 10s rather than 1s. (Be sure all of the “10s” are highlighted on your Growing Number Line for reference, as needed.) B Math Masters, p. 32 Teaching Options ENRICHMENT ► Playing Addition Top-It (Center Activity Cards, 16) Children add the numbers on two overturned cards; the higher sum wins. (Begin with 0–5 cards and gradually increase numbers.) Dots on the cards can help with addition. See Project 3, Fun with Games, for other addition and subtraction games. EXTRA PRACTICE ► Playing Number Card Games In addition to the Top-It variations, provide card games such as Go Fish. Also encourage children to play the card games from Activity 3-9, page 158. 191 32 Ongoing Assessment: Recognizing Student Achievement Use Top-It to assess children’s ability to identify the smaller and larger number in a pair. Children are making adequate progress if they can do this for the numbers 0–20. Some children may be able to compare larger numbers.
