Title – Probability with Bears
By – Floy Gutierrez
Primary Subject – Math
Grade Level – 1st

Texas Essential Knowledge Skills:

Math (1.9)(B) – organize data to construct real-object graphs, picture graphs, and bar-type graphs

Student Learning Objectives:

• identify events as certain or impossible such as drawing one red bear from a box of yellow bears
• recognize bar-type graphs
• organize collected data

List of Materials:

• graphing bears worksheets
• markers
• 4 boxes of bears (red ones, blue ones, yellow ones, green ones, etc.)
• picture of the colorful bears
• example graph

Pre-activity Preparation:

• Make and copy the “Graphing Bears” worksheets
• Gather the markers
• Prepare boxes of bears in different colors
• Make an example graph

Transition:

• Students are seated at their desk during the instruction
• Then students are grouped and released quietly to their work stations

Introduction:

“Who likes bears?”

Procedure:

1. Have students sit at their desks, then begin instruction:
   • “Who likes bears?”
   • Show picture of the colorful bears.
   • Students will answer immediately, so remind them to raise their hand.
2. Introduce Math Center:
   • “I have a Math Center for you.”
   • Ask them if they have any ideas on how they can do math with bears.
3. Explain what they will be doing in the center:
   • “Your math center is really fun – you will check for the probability of grabbing a yellow bear in a box full of bears of different colors.”
   • “You will also graph this probability on your worksheet.”
   • “You will open up the boxes – one box per group.”
   • “After you are done separating them, count how many bears you have in each color group.
   • “Graph your results – each bear will have a spot in your worksheet.” Show them an example.
   • Show students where the center is. Stand by for questions.

Closure:

“What are you doing in your center? What did you learn?”
