We are now beginning a mathematics unit on Numbers to 1000.  In this unit, your child will: ·         Show a 3-digit number in different ways, using concrete materials, pictures, words, and numbers. ·         Compare and order 2-digit and 3-digit numbers. ·         Skip count by 5s, 10s, and 100s forward and backward to 1000. ·         Skip count by 3s, 4s, and 25s forward and backward to 1000. ·         Estimate how many items are in a large collection by comparing it to a known  quantity.   Example: Show ten buttons - If this is 10 buttons, how many are in this big pile of   buttons?   Here are some activities you can do at home to support this learning:               -  Use play money to model numbers and to develop understanding of trading or                  grouping. For example, show that $34 can be modeled as $300 + $40 + $2. Using                   play bills for $1, $10, and $100 helps to reinforce place value.                - Play a number comparison game: Remove the tens and face cards from a deck of                  regular playing cards.  Deal 3 cards to each player.  Each player uses the cards                  to make the greatest possible 3-digit number. The person with the greater number                  gets a point. Repeat. The first player to get 10 points is the winner. Play the                   game again, this time making the least number possible.      Students will also work on basic facts. They will be using various mental math   strategies to help them recall the facts quickly. They will learn to apply mental math      strategies such as :            -  Doubles (Ex: If I know that 6+6=12, then 7+6 is one more, so it would be 13).            -  Commutative Property (For 3+9, think 9+3. They give the same answer).            -  Making 10 (Ex: 8+6 – Think 8 + 2 + 4; 8 + 2 = 10, then 10 + 4 = 14).
