Masking Tape Bar Graph
Suggested age for this project: 6-12 years old
- 1 inch wide colored masking tape, 7 colors
- Marking pen such as a Sharpie
- A standard 6 sided die
- Clip board or other smooth surface to hold your data markers
Let's Make It!
Step 1: Create Your Data Marker Squares
Take a piece of masking tape and stick it on a ruler, allowing the ruler’s measurements to show at the top.
Draw a line on your tape at 1 inch measurements.
Stick the tape squares on the clip board.
Repeat these steps until you have 12 squares of tape in each of your 6 colors.
Step 2: Color Your Die
Step 3: Tape the Graph Components on the Floor
Along the bottom edge of the graph (more commonly referred to as the x axis or horizontal axis), mark the space for each bar color and label it. I just used my Sharpie to write the ﬁrst letter of each color.
Along the left edge of the graph (more commonly referred to as the y axis or vertical axis) use a ruler to mark 1 inch increments and label them 1 – 20 beginning at the bottom of the axis.
Step 4: Predict
Step 5: Collect Data
Whatever color it lands on, take a tape square of the same color and put it in the corresponding area of the graph, starting at the bottom.
Keep going until you have rolled the die and recorded the data 20 times.
Step 6: What Does Your Data "Say"?
Here are some great discussion questions:
- How many times did each color show up in our 20 rolls?
- Are your predictions reflected in the data?
- Are the probabilities reflected in the data?
- What may have influenced your results?
- Would you get the same results if you did the whole thing over again?
- How can we use this type of graph to measure something out in the real world?
