What Your Child Will Learn

and record each with an equation (e.g., 18 = 10 + 8) (K.NBT.1)
 
Quarter 3 and 4
 

Vocabulary

  • Place Value: The value of the place of the digit in the number (For example: in 27, 2 is in the 10's place and is worth 20)
  • Compose: Putting numbers together to make a new number (For example: 5+10=15)
  • Decompose: Breaking a number apart (For example: 15=8+7)
  • Equation: A mathematical statement containing an equal sign, to show that two expressions are equal
  • Add: To join two or more numbers
  • Subtract: To take one quantity away from another
  • Ten: A group of ten ones

 

Activities at Home

  • Use a stick of spaghetti to represent 10 and marshmallows to represent ones. Represent the numbers 12, 13, and 16 with the spaghetti and marshmallows.
  • Use a popsicle stick to represent a ten and beans to represent ones. Using a deck of cards, give your child a 10 card, and draw another number card, then add the numbers together and show the number with sticks and beans.
  • Walk from one end of the kitchen to the other and count how many steps, then show how many steps were taken with sticks and beans.
