Key Concepts

  • Division as sharing
  • Equal groups
  • Remainders

Learning Objectives

  • Students will be able to divide a set of objects into equal groups.
  • Students will be able to identify the number of objects in each group after dividing.
  • Students will be able to understand the concept of a remainder.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what 'sharing' means to them. Talk about how sharing should be fair, meaning everyone gets the same amount. Introduce the idea that in math, sharing is called dividing.
  • Jelly Bean Sharing (10 mins)
    Watch the section of the video where Mrs. Lawson shares jelly beans. Pause the video at different points to ask students questions. For example, when she has 28 jelly beans and 4 bowls, ask 'How many jelly beans will each friend get?' before she shows the answer. Discuss the concept of dividing the jelly beans equally among the bowls.
  • Easter Egg Sharing (10 mins)
    Watch the part of the video where Mrs. Lawson shares Easter eggs. Again, pause the video to predict how many eggs each friend will get. Emphasize how she shares one egg at a time into each bowl to make sure it's even.
  • Practice Sharing (10 mins)
    Give each student a small number of objects (e.g., counters, blocks, or crayons) and ask them to divide them into groups. Start with dividing them into 2 groups, then 3, and then 4. Help them if needed.
  • Wrap up (5 mins)
    Review what they learned. Ask them, 'What does it mean to divide?' and 'How do we make sure we are sharing fairly?'

Interactive Exercises

  • Sharing Game
    Give each student a set number of objects (e.g., 10-15 small toys). Have them roll a die to determine how many groups they need to divide the objects into. They can then physically move the objects into the groups. If there are leftovers then explain that the left overs are called remainders.
  • Drawing Groups
    Give each student a worksheet with different numbers of circles. Have them draw a set number of objects within the circles. For example, give them 12 circles and ask them to draw 2 dots in each circle. Ask them how many dots they drew in total. Change the instruction to draw 3 dots per circle. Practice counting up the number of groups and total number of objects per group.

Discussion Questions

  • What does it mean to share fairly?
  • Can you think of a time when you shared something with a friend?
  • What happens if you can't divide things equally? (Introduce remainder)

Educational Standards

CCSS.Math.Content.1.OA.A.1:Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. CCSS.Math.Content.1.OA.C.6:Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
