INTERPRETING PICTURE GRAPHS GRADE 3

Hello, How are you doing? Today, we are going to start a new lesson on Pictograph.

Key Key indicates how many items each symbol stands for. Example- Each key ● (symbol) represents 3 students. Favorite Food of Third grade students FoodNumber of students Burger● ● Sandwich● ● ● Pizza●

Pictograph A graph that shows data by using symbols. Example- The following pictograph shows the number of books sold by a Book Store in 3 months. Each ◊ represents 10 books. MonthNumber of booksSymbols March50◊ ◊ ◊ ◊ ◊ April40◊ ◊ may30◊ ◊ ◊

Important Tips In Pictographs, one symbol can indicate only one item. To find the total number of items, add the number of all the items.

Model Pictograph Step 1: Write the title at the top of the graph. Write a label for each row. Step 2: List the items. Step 3: Use symbols to represent equal number of items. Step 4: Use a key to tell the number each symbol represent.

Make a Pictograph for the following graph. MonthSale of Burgers June65 July70 August55

Solution Sale of burgers Each ● represents 10 burgers and ◦ represents 5 burgers MonthSale of burgers June●●●●●●◦ July●●●●●●● August●●●●●◦

If 20 more burgers were sold in June, how would the pictograph change? Two (2) more ● symbols were introduced in the month of June. MonthSale of burgers June●●●●●●●●◦ July●●●●●●● August●●●●●◦
