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
- 4 boxes of bears (red ones, blue ones, yellow ones, green ones, etc.)
- picture of the colorful bears
- example graph
- Make and copy the “Graphing Bears” worksheets
- Gather the markers
- Prepare boxes of bears in different colors
- Make an example graph
- Students are seated at their desk during the instruction

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