Students identify the ratios of trig identities. In this geometry instructional activity, students solve the missing sides and angles of triangles using trig ratios. They relate the graphs and waves to real life scenarios.

In this math worksheet, students use a variety of non-standard measurements units to find the lengths of objects on paper and around the room. Students first make an estimate, then measure with different units.

Students aim to explain the need for standardization of units of measurement. They pose their own standards for the value of a kilogram and compare them with the currently used standard.

Students analyze timber and use measuring techniques to figure board feet.  In this investigative lesson students learn why accurate measurements are important and how to convert standing timber to board feet. 

Second graders review their knowledge of measurement by making a concept web. They write the measurement words on chart paper and discuss them. They use Kidspiration to make the web using the computer. They add new words as they proceed...

Learners identify various angles and how to measure each type. They use a protractor to measure each of the angles. Students also write the name of the angle and identify the number of degrees for each.

Using a Smart Board, or a plain ol' white board or chalkboard, the teacher pulls up a grid and demonstrates how squares and rectangles can be divided up into equal parts. The class will get their own graph paper to draw shapes and divide...

Fourth graders participate in a teacher-led discussion about temperature--hot and cold. Each group of students is assigned specific materials for their lab experiment. They record temperatures measured in their journals and then plot...

Explore the concept of multiplication by using arrays. Classmates use arrays to gain a better understanding of multiplication. They break arrays apart to model the distributive property of multiplication over addition. The relationship...

How well does your class understand the concept of correlation? Use an activity to explore different methods of calculating correlation. Working alone and then in groups, your class will make decisions on what math to apply to the...

Kindergarteners use worms, puppets or other props to practice counting to 100. First, they listen to a read aloud of Count Worms by Roger Hargeaves. A worm pattern is used to count to 100, with each segment of the worm...

Learners use index cards, counting cubes, and their own understanding to identify how division problems can be solved by using multiplication. In this division lesson plan, students use their multiplication skills to solve division...

In this measurements worksheet, students read the word problems and use the measurements within the problem to solve the six word problems.

Explore the use of non-standard units for measuring volume with elementary learners. They fill a container and count the number used using cups, spoons, and bottles, build with blocks and count the number of blocks used, and compare and...

A bite of bits. The first lesson plan in a unit of 15 introduces the class to the byte. Pupils learn about other standard units for measuring file sizes, develop an understanding of relative sizes and the kind of units used to...

How efficient is a motor in a LEGO set? Future engineers conduct an activity where a LEGO motor-generator system raises an object to a specified height. They then show what they learned and use their measurements to calculate the energy...

Young scholars explore the concept of measurement as it relates to equivalencies. They complete simple conversions using visual models of measurement units, and  record their answers in a two-column table.

In order to learn about the Pythagorean Theorem, young mathematicians investigate relations and patterns between different sides of a right triangle to look for possible relations among the squared sides. Once they have established the...

Elapsed time is a skill developed by the single question that is the center of this activity. Fifth graders are asked to find out the time that is 2011 minutes after the beginning of 2011. This question addresses the standard that...

Sports fans will really enjoy this unit conversion assignment. A table of standard measurements for football-related equipment is presented as the data for solving six word problems. For all of the problems, players will need to convert...

Scholars investigate levels of nitrogen dioxide in the Pacific Northwest by examining the role of nitrogen in air pollution and how remote sensing can be used to measure nitrogen levels. An Excel spreadsheet calculates the difference...

Students gather historical snow cover and temperature data from the MY NASA DATA Web site. They compare this data to data gathered using ground measurements from the ALISON Web site for Shageluk Lake. They graph both sets of data and...

Kids observe, classify, and measure tree leaves with a scientific eye. They examine leaves, group them according their attributes, and use standard units of measurement as they compare their sizes. They access a web site to learn how...

A transformational assessment determines how far pupils are advancing toward mastering complex and matrix standards. The assessment checks the learners' understanding of linear transformations, complex numbers and the complex plane,...
