Length Websites


K-2

Big and Small
A resource which looks at mathematical vocabulary 'big' and 'small', 'short' and 'tall'. It is introduced through a story and then pupils can complete sorting and ordering activities. There are accompanying worksheets. Nice audio feedback. 3 different activities: Intro, Main, Plenary

The Zoo
A wonderful site for developing and reinforcing mathematical vocabulary such as shortest, tallest and smallest. Excellent sorting activities and children can match parent and young. The zoo animals are located higher on the screen and may be difficult to reach for some children. Four different activities. Also some Science concepts involved, but we liked the Math concepts more.

Lecky Compares
A colorful, simple site where children need to compare and order different things. It covers mathematical vocabulary such as longest, shortest, widest, biggest and smallest. "Cheering" feedback. A lovely British accent!

Measuring Lines
Demonstrate how to measure lines in cm with a ruler and random lines. Very little feedback for responses, but good practice. Students can write the answer on the SMARTboard using the "Shortcut" keyboard.

Reading Scales 2
More practice in reading various instruments: a weather station, in the lab, and in the workshop. Unlike the original Reading Scales activity, however, all of the readings are generated randomly, and they may or may not align with the scales markings.

Teaching Measures: Length
WOW! There are 4 pages of activities with supporting worksheets on this site! Some of the activities allow a choice of ruler size (either 15 cm or 30 cm). More advanced activities involve the conversion of units, and fractions to decimals. You won't be disappointed in this site, unless your students are distracted by the "FOR EVALUATION ONLY" watermark.

Measures and Weights
On this very attractive, colorful website from the BBC, students must measure the length of a package in cm, then weigh the package in grams or kilograms, and finally determine the correct postage stamp to put on the package from a table of sizes and weights. Some conversion of cm to m or g to kg is required at the more difficult levels.

Bucky's Geometry Workshop
NOTE: This is no longer a free site. On this excellent and colorful site are 6 different topic areas including "Angles and Triangles" and "Perimeters and Areas." Each activity has its own workspace with drawing and measuring tools. You can create as many separate pages as you like. You can also click on "Give Me A Challenge" in the upper right corner of the work area and be presented with a multiple choice question related to the topic you are investigating. Bucky reads each question aloud and provides encouraging audio feedback. You will want to explore each topic to determine the appropriate grade level.

Animal Height Labels
Another great site from the UK. There are 5 animals to measure. After measuring the animal students can label it with the appropriate height.

Animal Length Labels
There are so many wonderful sites from the UK! Another 5 animals to measure and label, similar to the previously listed site.

Comparing Jungle Animals (Height)
Students are asked to estimate the height of one animal in units of another animal (i.e. a zebra is as tall as how many macaws). They can then test their guess by stacking the animals.

Comparing Jungle Animals (Length)
Similar to the previous site, students estimate how long an animal is in units of another animal, and then test their guess.

Comparing Line Lengths
Given 3 colorful lines, students must complete a sentence that compares and describes the lengths of each line. You may choose to use either the word "shorter" or "longer" i.e.-- orange is cm shorter than green.

At the Vets

Too clever! Acting as a veterinarian, students weigh and measure the length and height of a variety of pets.

Measuring Lines- Make 1m
Students join two or more lines to make 1 meter.

Ostrich Long Jump
Too fun! Three ostriches compete in a long jump. Students use a tape measure to record the length of each jump in meters.

How Big?
Students are asked to compare the relative sizes of animals, i.e. "A donkey is larger than _" or "A cat is smaller than."

3-5

Geoboard
From the National Library of Virtual Manipulatives (NLVM). A very useful tool for demonstrating shapes, perimeters, and areas. Great practice for calculating perimeter and area, and this site will display the perimeters and areas for you if you click the "Measures" button.

Area
Another Geoboard-type option, this interactive tool can be used in a variety of contexts: multiplication arrays, finding different shapes with the same area. Many different display options including "rubber bands", colored areas, grids give this site a lot of flexibility.

Understanding Measures
A great website, but it requires typing or writing the answers in with the correct spelling of the units, not the abbreviation. And British spellings are used! Therefore, this site will require more time and could be frustrating when using "litres" or "metres."

Measuring Lines
Demonstrate how to measure lines in cm with a ruler and random lines. Very little feedback for responses, but good practice. Students can write the answer on the SMARTboard using the "Shortcut" keyboard.

Throwing Challenge
This fun game has 3 different athletes throwing a javelin, caber, and shot putt to random distances, either in whole numbers or to one decimal place. Each level has both a "read" game and an "estimate" game and you may select either 5 or 10 questions per game.

Reading Scales 2
More practice in reading various instruments: a weather station, in the lab, and in the workshop. Unlike the original Reading Scales activity, however, all of the readings are generated randomly, and they may or may not align with the scales markings.

Measure and Interval Maker
Students create their own ruler or scale to measure weight, height and length. They choose the interval for major divisions on the instrument, and even the number of minor intervals between major intervals. They can then weigh or measure a variety of objects using the scale they designed.
