Ten-Coin Toss
Family Note
By the end of Kindergarten, children should be able to find number pairs that add to 10, such as 9 and 1, 8 and 2, 7 and 3, and so on. Children are beginning to develop this understanding by playing games with sets of ten and by using ten frames, such as the one below. Do not expect your child to memorize the number pairs at this point. Children will have plenty of practice finding number pairs that add to 10 throughout the year.
Question 1.
Gently toss 10 pennies. Sort the pennies into groups of “heads” and “tails” and put them on the ten frame.
Count the number of heads and the number of tails. You may want to record the numbers you find on the back of this page.
Repeat at least three more times.
Answer:
Explanation :
4 times the 10 pennies were tossed and the respective head and tale is written in the given tabular column. then total number of heads and total number of tales are tossed are counted and written below as shown in the above Figure .

Longer or Shorter?
Family Note
Your child is learning about length measurement by comparing objects and describing them as longer and shorter than other objects. In Kindergarten we focus on direct comparisons of length to prepare children to use measuring tools later. Help your child line up the end of his or her arm (at the longest finger) with the end of the object being compared. This technique will be helpful later when your child learns to line up objects with the end of a ruler or other measuring tool.
Question 1.
Compare the length of your arm (starting from the tip of your longest finger) to objects at home or outside.
Which objects are shorter than your arm?

Monster Squeeze
Family Note
Monster Squeeze is a game that reinforces number recognition and the concepts of greater and less.
Directions are provided below, but let your child take the lead in teaching you the game.
Materials Two monsters and a 1–10 number line
Players 2
Object To guess the mystery number
Directions
- Player 1 places one monster at each end of the number line, facing the other. The same player chooses a mystery number between 1 and 10 and writes it on a piece of paper.
- Player 2 guesses a number.
- Player 1 says whether the number guessed is too low or too high and covers the number with a monster. (The left monster covers the number if the guess was too low. The right monster covers the number if the guess was too high.)
Example: If the mystery number is 6 and the guess is 3, the left monster moves up the number line to cover the 3. If the guess is 8, the right monster moves down the number line to cover the 8.
- Players keep guessing and moving the monsters until the mystery number is guessed, or “squeezed,” between the monsters!
Question 1.
Cut out the monsters and the number line. Use them to teach someone to play Monster Squeeze.
Answer:
Explanation :
Step 1 :
Both monsters are are placed on the ends that is one monster on left end and other monster on Right end
Step 2 :

In the above one the First Guess made is 2 – low guess so, Left side monster is kept on 2 .
Step 3 :
Guess 2 : 7 – High Guess so , Right side Monster is placed on 7
Step 4 :
Guess 3 : 5 – High Guess so, Right side Monster is moved from 7 to 5 .
