PictoGraphs CCSS: 3.MD.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.3.MD.3 SFO: -I can read and analyze pictographs. -I can create a pictograph to represent a given set of data. Essential Questions: -What is a pictograph? -What is the difference between a pictograph and a bar graph? -Why do we use pictographs? -How can I read and interpret a pictograph? Teacher Input: -Slide 1: Introduce pictographs using Power Point. Go over the lessons objectives with the students. -Slide 2: Ask students to look at the pictograph and tell what they notice -Slide 3: Discuss the important components of a pictograph: title, symbols, labels, key -Slide 4: Guided Practice: Display a pictograph and have students read and analyze it by answering questions. -Slide 5: Independent Practice: Collect a class set of data. For example: favorite football team, favorite candy, favorite food, favorite subject etc. Collect the data and have students record on the left side of their notebook. Tell students that they will then create a pictograph using the class set of data. Tell them to make sure they include a title, symbols, label, and key. Tell students to create 3 questions to go with their pictograph. Give students 2 two-step questions to answer based on the data. Closing: Discuss what they learned about bar graphs from yesterday and pictographs today and discuss the differences in both graphs. Assessment: Left side of interactive notebook

Pictographs Objective(s): -I can understand and identify the parts that make up a pictograph. -I can read and understand a pictograph by correctly answering questions -I can create my own pictograph after collecting a set of data.

A graph that uses symbols to represent data. What do you notice about these pictographs?

Parts of a pictograph graph Title – Every pictograph should have a title that fits the data. Symbols - Pictographs have symbols or pictures to represent the data. Key – Pictographs have a key to show what each symbol/picture represents. Be careful because not every picture/symbol represents 1! Labels – Pictographs have labels for their pictures or symbols It is very important to look at the key and determine how many pieces each symbol represents.

It is very important to remember the symbol in the key represents multiple pieces. If the data does not match the number of the symbol, the symbol must be cut to represent the fraction of the piece. Cardinal Dove Crow Blue Jay = 2 birds Since each represents 2 birds, the half bird would represent one. There were 3 Cardinals, and 9 Crows.

Guided Practice Read and Interpret the Pictograph In January _______ apples were sold How many more were sold in February than in April? __________

Guided Practice 1.How many members were part of the chess club? ________ 2.How many more students were in the math club than the Hobby club? _______

Left Side: Assessment Create a survey question to ask the class. Examples are favorite NFL football team, favorite ice cream flavor, favorite subject in school, favorite sport. We will record the data as a class and you will create a pictograph representing the data. You will then answer 4 of my questions and create one of your own about your pictograph. Remember your pictograph must include: -Title -Symbols (must represent your data) -Labels -Key

Line Plots CCSS: 3.MD.B.4 Objectives: We will interpret data on a line plot. We will create a line plot to represent a set of data. EQ: How might line plots be useful? How can I interpret data on a line plot? Teacher Input: 1. Using the power point, display a line plot and have the students point out things that they notice. 2. Discuss the components of a line plot. 3. Have students analyze a line plot and answer the questions posed on slide four. (Guided Practice) 4. Collect a class set of data. 5. Write down the data on the board. Independent: 1. (Left-side) Have the students create a line plot to represent the amount of votes for each food type. Make sure they include all the components to the line plot. Closing: Discuss how line plots may be useful in the real world. Assessment: Left side of the interactive notebook.

Components to a Line Plot Title Labels Scale—may show a range of numbers or categories. A range shows from the minimum value to the maximum value. Line plot---is a number line that represents data that is recorded in experiments or surveys. A line plot uses x or other marks to show frequency. It collects and classifies the data very quickly. X---represents one number in the data

Be Careful of the Key! Sometimes, the x can represent more than just one! For instance, on this line plot, you might say that 2 students have 8 candy bars. However, in this line plot, the key explains that x = 2. In this line plot, how many students have 8 candy bars? X = 2

Analyze the Data 1. How many students have 5 candy bars? 2. How many more students are there that have 5 candy bars than students with 3 candy bars? 3. How many students have 8 candy bars? 4. How many candy bars do they have total? How many more candy bars would they need in order to have 132 total? X = 2

Left Side: Independent Practice  Using this menu, create a line plot that shows how many food items fall within the following price ranges: $0 – $0.99 $1.00 – $1.99 $ $2.99 $ $3.99 $ $4.99 $5.00 or more  Then, create 2 addition or subtraction problems to go with the bar graph.
