**Tally & Number Match Game**

Note to Families

Play a matching game with the tally cards and the number cards. If your child needs practice recognizing the groups of tally sticks without counting, try “flashing” the cards—showing them for just three seconds. The two worksheets offer more practice in counting and writing numbers.

Materials

- Tally & Number Match Game,
- scissors
- envelope (to store game cards)

1. Cut apart the tally and number cards on pages 3 and 4.

2. Lay all of the number cards face-up on one side and all of the tally cards face-up on the other side.

3. Can you find the matching pairs?

4. Once finding the matching pairs feels easy, turn all of the cards face-down.

5. Take turns turning one card from each group face-up. Is it a matching pair?

- If it is, take those cards and take another turn.
- If they don’t match, turn them back over and give your partner a turn.
- Try to remember where each card is located.

6. The player with the most cards at the end of the game wins.

7. **CHALLENGE**

- If your child can easily match the tally cards with the number cards, go to the “face-down” version of the game right away.
- Another challenging activity would be to put the tally cards in order from greatest to least and the number cards from least to greatest.

8. Play the game a few times this week. Save the cards so you can play again in a few weeks.

9. Have your child complete the worksheets on pages 5 and 6, and return them to the teacher.

**Butterfly Countdown**

Note to Families

As you and your child act out counting down from 10 with paper butterflies, your child will be working with the big idea of subtracting 1. There are also two worksheets, one on addition and one on subtraction.

**Materials**

- Butterfly Countdown
- crayons (optional)
- scissors

Instructions

1. Color the page of butterfly cards if you like, and cut them out.

2. Spread the 10 butterfly cards out in a line.

3. Read the Butterfly Countdown poem one verse at a time, stopping before you say the final word (the number of butterflies left).

4. Have your child take one butterfly away and ask, “How many are left?” Read the verse again, this time including the final word.

5. Continue reading the poem until there are no more butterflies left.

Note Another way to do this, without reading the poem, would be to just start with 10 butterflies and take away 1 at a time, saying how many are left each time.

6. Try some “mental math” now or at another time. (For example: Imagine 7 butterflies hovering over some flowers. If 1 flies away, how many will be left?)

Note If your child is more comfortable using the paper butterflies, be sure to get them out again.

7. Have your child complete the worksheets on pages 4 and 5 and return them to the teacher.
