Firing up Fourth

 

          Students will look for arrays in objects such as floor tiles, windows, and checker boards. You may want to point out arrays you see. To practice using arrays with your child at home, use any small objects such as beans, macaroni, or pennies.  Mastery of basic multiplication facts is very important. We have shared memory strategies for 3s, 4s, 5s, 8s, 9s and tens. If your child would like copies of cartoon stories for the remaining "toughies" please have them ask me for those sheets.

Activities

  • Help your child to make the connection between their own knowledge and their experiences, both in school and outside of school, students learn basic math skills in meaningful contexts so that the mathematics becomes real.

  • Practice basic skills frequently in a variety of engaging ways. Have a family game night to reinforce skills using one of the games mentioned above.

  • Have your child revisit previously learned concepts by explaining a page or previously learned concept to an extended family member or friend.
