In third grade we get to liven up our bar chart lessons by taking advantage of our students’ new familiarity with multiplication and division. By the end of third grade, the Common Core recommends that common core math worksheets 3rd grade pdf know from memory all products of two one digit numbers.

Objective In this 3rd grade bar chart lesson, students will learn to analyze and understand data presented on a scaled bar chart. They will learn how to do both simple and multi-step comparing problems using the bar chart. Procedure Start this lesson with a bit of storytelling. Once upon a time, far away, in the wild open steppe land of Mongolia, two children lived with their old grandfather and grandmother in a little round tent made of felt.

That, and the camels, yaks, sheep and horses which made up the family wealth. It was Temuujin’s job to take the horses and yaks to pasture every morning, and Zolzaya, his little sister, took the sheep and goats to the green grass on the other side of the hill. Grandma and Grandpa were getting old, and though they still hobbled around, checked everything, and told the two children what to do, they were past the age for active work. Then came the spring when Grandpa’s legs were so bad he could not make his rounds of the herds as he had used to. He had to stay in his bed by the fire, and the furthest he could move was to his seat by the fire. He worried about his herds, and though Temuujin and Zolzaya knew everything was going well, he wouldn’t believe them when they told him that. He would ask questions about numbers—how many more kids are there than lambs?

One day Temuujin and Zolzaya decided to do something special to give their grandfather all the information he wanted about the animals. They would count all the lambs, kids, foals, calves and baby camels, and mark down the numbers in a tally chart. Then they would make a bar graph for their grandfather, so he could see exactly how many animals he had without having to go outdoors. They were quite sure that this would make their grandfather very, very, happy, and they had exactly one sheet of graph paper to draw their bar graph on. But when they came in from counting, both Temuujin and Zolzaya had very somber faces.

This is what their numbers looked like. Display a simple sheet of large-squared graph paper , with ten squares each way. How could they put their data on this little sheet? Stop here, and give your students a chance to discuss the problem.

After a discussion break, ask for possible solutions. Temuujin and Zolzaya realized there was only one thing to do: they could scale their bar graph so that each block on the graph paper, instead of meaning 1 animal, meant five. This made some of their numbers very easy to work with. The calves, for instance, being exactly fifteen, would be represented by a bar exactly three squares tall on the bar graph. Ask any students who have solutions to share them with the class.

So this is what Temuujin and Zolzaya’s graph looked like. They were very pleased when it was done, and carried it proudly in to their grandfather. And after that, they could answer all his questions with just a moment’s hesitation, whenever he asked them about the numbers of animals. Before you go into these questions, the initial data you put on the blackboard should be erased, so that students are encouraged to base their arithmetic on the graph rather than on the raw numbers. The first question he asked was, how many more kids are there than lambs?

So he could see exactly how many animals he had without having to go outdoors. Objective In this 3rd grade bar chart lesson, so this is what Temuujin and Zolzaya’s graph looked like. They were quite sure that this would make their grandfather very, how could they put their data on this little sheet? In the wild open steppe land of Mongolia, and come in with your ideas only after they have it worked out.
