Skettles Graphing and Probability

Graphing Grade 3

Objective: Pass Skill: 5.1c Data Analysis & Probability – Construct a bar graph or pictograph with labels and title for a set of data.

Students will demonstrate the ability to: 1. estimate/predict items to classify 2. count and sort items by color. 3. record data on a chart 4. use data from a chart to create a bar graph 5. analyze and interpret data 6. compare with students the number of colors each student is likely to receive 7. use data to determine probability

Materials:

Instructional sheet including sorting mat and bar graph form 1 bag Skittles for each student Pencil

Anticipatory Set:

Students will be required to make predictions as to the number and color of skittles that are contained in each bag. This will provide a hands on approach and connection in the learning process. Students will see the connection in collecting, analyzing, and interpreting data, and to improve decision making skills through the use of making predictions. Initially we will discuss the use of graphs and how we can use them to analyze sets of data.

Inquiry Based Instruction & Guided Practice:

1. Give each pair of students a bag of Skittles. 2. Students will predict the number and color of Skittles contain in their bag and record on their data sheet. 3. Students will open bag of Skittles and begin to count and sort candies according to color on their sorting mat. 4. Students will record and compare number of each color with partner. 5. Repeat step 4 and use 2 additional partners. 6. Next, students will use bar graph to place Skittles to complete the bar graph. 7. Make a class tally sheet to reflect the number and color of Skittles for the class. Closure:

Review the results of the bar graph and why we would use a bar graph for interpreting data. Discuss other ways/items we could use to create a bar graph. Make predictions as to what colors of Skittles we would receive if give another bag.

Independent Practice:

One the following day we will review previous day lesson and work independently.

1. Give each student one small bag of colored .beads 2. Ask the students to sort and classify beads according to color. 3. Students will then record their data on their sorting sheet. 4. Students will create bar graph according to the data.

Assessment and Follow-Up:

OSDE item specs will be used to assess and identify students that have mastered the skill being taught. Those that do not show mastery will be re-taught in a small group setting and will be reinforced through the use of computer based programs.

Estimating Do not open your bag yet. Guess how many Skittles are in the bag. ______

Open your bag, count the Skittles. How many Skittles are in the bag? ______

How far off was your guess (difference)? ______Sorting Use the sorting sheet provided in this packet. Put your Skittles into sets by color: G= Green R= Red P= Purple O= Orange Y= Yellow

Write the number of Skittles you have in each set.
