Construct and read simple graphs from given information to solve problems.
Construct and read a histogram.
Understand that histograms help to measure the frequency of data ranges.
Understand that a graph is a visual representation of data.
Become familiar with the vocabulary associated with graphs: unit, scale, title and labels.
Histogram, Title, Labels, Data, Frequency
1. Students constructed a histogram based off data given.
2. Students matched data with the corresponding histogram graph.
3. Students read the histogram and answered questions based on the data given.
Have students give out a survey to 20 people who have dogs. Ask each of them what the weight of their dog is. After gathering data from all 20, have students create a histogram. Make sure the have title, labels, and color their histogram.
1. What is your title of the histogram? What are the labels?
Estimate a given quantity based on place-value understandings.
Understand that rounding and estimation are a way to quickly check the accuracy of computations.
Understand that you can use estimation when an exact answer is not needed.
Estimate, Round, Nearest 10, Nearest 100, Exact
1. Students solved a variety of addition and subtraction problems using estimation. After solving using estimation, students colored the corresponding aswer with the color that matched.
2. Students solved multiplication problems using estimation (rounding to the nearest 10 and 100).
1. Show students an ad in the newspaper from a market. Give students a list of items to buy. Tell them to estimate how much money they would need in order to get all the items.
1. What should you round the numbers to? Round up or down on the dollar amount?
