Mia's pet lizard has grown a lot since he was a baby and she needs help measuring his length now that he's an adult. After choosing the best tool for the job, RJ goes step by step through the measurement process, modeling how to use both...

Fifth graders complete nine problems in which they work with converting customary units of length such as feet to yards, and yards to miles. They compare measurements using inequality signs in six examples, and answer two test prep...

Use these worksheets during your equivalent length unit. There are three separate worksheets with 10-12 problems each. Your class must fill in the appropriate number that is equivalent to the one presented. A conversion cheat sheet is...

How do you find arc lengths and areas of sectors of circles? Young mathematicians investigate the relationship between the radius, central angle, and length of intercepted arc. They then learn how to determine the area of sectors of...

Without using a ruler, learners estimate the relative length of various lines in these three scenarios. The first two are set up as maps, with learners determining the shortest and longest distances from one position to another. The last...

Here is an excellent lesson for young learners who are just beginning to explore the concept of using units to measure length. They rotate through four classroom centers in order to gain practice in utilizing this important skill.

Without measuring, can estimators determine which string is the longest? The shortest? There are two sets of strings here for learners to evaluate, circling the shortest in the first set and the longest in the second. Next, they eyeball...

A visual measuring exercise that lends itself nicely to an all-class warm up, especially as it doesn't provide room for scholars to write in answers on the sheet itself. They examine 10 rulers and determine the length in either inches,...

If my dog is 36 inches long, what is his length in feet? There are 24 measurement-conversion problems here involving inches, feet, yards, and miles. Two example word problems walk learners through this process before they try...

Use this converting units of length worksheet to have your charges fill out a table, find the perimeters to three shapes and calculate the answers to three word problems.

Viewers learn how to apply proportional reasoning to find area of sectors and arc lengths with a video that starts off explaining how to find the areas of circle sectors and the lengths of arcs. Scholars then practice solving problems...

Three rulers offer measuring practice with inches, centimeters, and millimeters. Scholars write four measurements, two of which involve fractional units. For the metric ruler they measure the same length in both centimeters and...

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

It won't take young mathematicians long to learn how to measure length with this fun, hands-on activity. Working in pairs, children use Unifix® or snap cubes to measure and record the lengths of different classroom objects. To extend the...

Customary units, also known as standard units of measurement, are the focus of a conversion brochure. Learners compare, identify, and convert customary units of length before folding the sheets into a brochure.

Match the length in more than one way. Pupils work in pairs to create equal lengths using different combinations of rods. The quick activity allows learners to develop a physical understanding of equality and realize there is more than...

What time is it when the arc length is pi? An interactive displays the measure of the angle created between the hour and minute hand of a clock. Pupils can set the clock to different hours and calculate the arc length based upon the radius.

An interactive presents two friends on a ferris wheel with the task of finding the distance between the them. Pupils create the chord between the two friends and calculate its lengths using trigonometric ratios.

Perimeter is the total distance around an object. One can find the perimeter of a rectangle or square by adding all four side lengths together. These worksheets require third graders to find the missing side length, given the...

In this customary length worksheet, students solve 5 multiple choice problems where they must choose the better estimate of customary length. Students then answer 9 fill in the blank problems and 1 word problem, where they must convert...

On this measurement hanodout, individuals review how to make conversions with customary units of length. They make conversions, compare lengths, and reason which unit of measure they would use for given items. To conclude the assignment,...

For this estimating lengths worksheet, students observe problems with pictures and lengths and choose the length that gives the best estimate. Students solve 9 problems.
