Students construct using Cabri software. In this geometry instructional activity, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired...

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Students explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...

Second graders design a scale model of a medieval castle and its surroundings including the following items: castle, moat, bailey, drawbridge, turrets, dungeon, grounds, and outer walls. A perfect lesson plan for those kids who are...

Students view a demonstration that simulates cloud formation. They read a poem about clouds, participate in a class demonstration using warm water and ice and write a paragraph summarizing their observations.

Learners discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Students identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.

High schoolers use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Students are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

Second graders publish a class cookbook of their own recipes. They explore the nutritional value of foods, calculate the measurements, and prepare a healthy recipe for the class.

Second graders get many opportunities to practice their measurement skills.

Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.

Students calculate the height and altitude of a pyramid. In this geometry lesson, students define the parts that make up a pyramid. They use the Pythagorean Theorem to find the missing parts of a pyramid.

Young scholars complete computer activities about estimating if items are more or less than a given amount. In this estimation lesson plan, students also estimate measurements around the classroom.

Second graders accurately measure the distances they and their classmates jump. They determine the mean, median and mode of specific jumps. They are required to have two measurements for each classmate, one for standing long jump and one...

Third graders estimate and measure the length of a whole color-segmented, candy gummy worm. Then, as students bite off each segment, they estimate, measure and record findings in an activity log.

Young scholars estimate, calculate, and count back the amount of change needed from purchases made during small group activities.

Third graders use nonstandard concrete methods to estimate and record measurements of their body.

Young scholars study units of measure like cups, pints, quarts and gallons. They work in groups to create their own mixtures of trail mix using the measuring cups. Then they make a gorilla puzzle using a gallon bottle.

Learners are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.

Students explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.

Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

Learners challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.

In these subtraction worksheets, students will subtract single and double digit subtrahends from double digit minuends. Students will need to regroup to solve.
