The Primary Focus in Third Grade

In grade three students will develop fluency of multiplication and division facts and continue to practice addition and subtraction facts. Students will learn that multiplication can be thought of in terms of equal groups and division can be thought of as sharing equal groups. Students are also presented with opportunities to use a variety of models for representing multiplication and division. In third grade students develop an understanding of fractions. The understanding that the size of a fractional part is dependent on the size of the whole is developed as they compare fractions. Area and perimeter will be taught. Students will describe 2-dimensional and 3-dimensional shapes and analyze two-dimensional shapes by their attributes.


Activities at Home

  • Roll 2 number cubes. Find the products of the factors. Make arrays to model the product.
  • Estimate the total cost of a shopping trip.
  • Roll a number cube and practice multiplying that number by ten. After mastery, try with two number cubes.
  • Play card games.
  • Show your child various numbers of dimes and have your child practice counting the amount of money (4 dimes x 10 cents = 40 cents).
  • Make arrays out of household items (e.g., pennies, beans, blocks)
  • Hunt for multiple sets of objects in the home. Use repeated addition and multiplication to find the totals.
  • Sort coins according to type, count the number of coins and then multiply to find the total value of pennies (x 1), nickels (x 5), dimes (x 10) and quarters (x 25).
  • Count quantities of items by 2’s, 3’s, 5’s, and 10’s.
  • Use a calculator to solve word problems using multiplication and division. For example, Callie wants to buy 20 apples that cost $ .19 each. What is the total cost of her purchase? Michael has 332 quarters. He wants to put them into groups of 4. How many groups will he make?
  • Act out division problems with counters. For example, Brad has 12 rabbits. He puts the same number of rabbits into each of 4 cages. How many rabbits does Brad put in each cage?
  • Roll 2 number cubes and write the fact families.
  • Ask your child to find the missing factor. For example, 5 x ___ = 75?
  • Share and discuss tables and graphs found in newspapers and magazines.
  • Conduct a survey among family members or friends and construct a bar graph or pictograph
  • Make a physical pictograph using real objects (e.g., fruits, vegetables, cereal, kitchen tools). Record the graph on paper. Change the scale to create a new pictograph.
  • Make records of important times of the day (wake-up, dinner, going to school, getting home from school, etc.) and practice telling how long between activities.
  • Calculate elapsed time by finding out how long it takes to complete daily activities (soccer practice, homework, take a shower, etc.)
  • Measure the perimeter and area of the rooms in your home to determine which rooms are the smallest and largest.
  • Use grid paper to make rectangles with the same perimeters. Determine the area of each rectangle.
  • Fill a small box with blocks (e.g., sugar cubes) to determine its volume. Brainstorm multiple strategies to determine the volume.

Homework

Homework addresses the skills and concepts from the previous unit and the current unit. Homework may not be directly related to the day's lesson. The skill practice from the current unit will be provided to students only after students have an understanding of a concept.
