Exploring Division

WNCP:

Outcome N4.5:

Demonstrate an understanding of division (1-digit divisor and up to 2-digit dividend) to solve problems by:

  • using personal strategies for dividing with and without concrete materials

  • estimating quotients

  • explaining the results of dividing by 1

  • solving problems involving division of whole numbers

  • relating division to multiplication

Indicators:

  1. Solve a division problem without a remainder using arrays or base ten materials.

  2. Solve a division problem with a remainder using arrays or base ten materials.

  3. Solve a division problem using a personal strategy and record the process symbolically.

Mathematical Processes:

Connections
Communication
Mental mathematics and estimation
Problem solving
Reasoning
Visualization

Activity/Lesson Ideas:  

  • Discuss the significance of beads with the students. For example, beading has been an important part of First Nations culture for approximately 8,000 years prior to European contact. Beads were made of shell, pearl, bone, teeth, stone and fossil stems. Glass beads became a part of First Nation and Métis culture when the explorers came from Europe and brought seed and glass beads as trading items.

  • Explain to students that each tribe distinct designs, patterns and approaches therefore collections of First Nations bead work art includes many different designs, styles, traditions and stitches. In Saskatchewan the Plains Cree uses a lot of symmetrical patterns and distinct geometrical shapes.

  • Have the students use four columns on the graph paper to simulate the loom as explained in a previous lesson. Using colored markers, pencil crayons or pony beads have the students create the following pattern:
beads
  • Ask the students:
    • If you continued the pattern and used 28 beads how many rows would you have on the loom? How many blue beads would you have on the loom?

    • If you had 35 beads, how many rows could you make? How many beads would be left over? (Reminder.)
  • Extensions
    • Imagine if the beads were numbered,
with numbers
    • In what row is the bead number 30.

    • In what row is the bead number 74? What color is the bead?
