Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

What if I can no longer justify area by counting squares? Lead a class discussion to find the area of a rectangular region with irrational side lengths. The class continues on with the idea of lower approximations and...

Are pyramids and cones similar in definition to prisms and cylinders? By examining the definitions, pupils determine that pyramids and cones are subsets of general cones. Working in groups, they continue to investigate the relationships...

Graph linear equations in standard form with one coefficient equal to zero. The lesson plan reviews graphing lines in standard form and moves to having y-coefficient zero. Pupils determine the orientation of the line and, through a...

Determine the slope when the unit rate is difficult to see. The 17th part of a 33-part series presents a situation that calls for a method to calculate the slope for any two points. It provides examples when the slope is hard to...

Create ratios using the boys and girls in the class. The first lesson in a 29-part series introduces ratios. Pupils learn to create ratios, write them, and model them with tape diagrams. Class members realize that there are different...

What city has the most consistent temperatures? Pupils use the mean and mean absolute deviation to describe various data sets including the average temperature in several cities. The 10th activity in the 22-part series asks learners to...

Rather than a activity, this teacher resource is a one-page, scripted answer sheet for a guided lesson on length word problems. First graders are asked to compare the length of a flower and a jar of jam with a number of unit boxes. While...

Help your young writers improve the clarity of their sentences by showing them how to create parallel structures as they construct sentences. Two exercises give kids practice identifying the correct parallel structure and crafting...

This task asks learners to prove that the segment joining the midpoints of two sides of a parallelogram is both congruent and parallel to an adjacent side of the parallelogram. The activity would be good to use in a discussion about how...

What better way to get your class interested in history than to embody important historical characters and make events come to life? Stage a realistic mock trial of the British soldiers accused of murdering five Bostonians after the...

From Brazil to Indonesia, young scientists investigate the geography and climate of the world's tropical rain forests with this collection of worksheets.

When we have learners with behavioral or special needs in is extremely important to be able to communicate effectively with parents at home. Here you'll find an A to Z checklist for you to fill out during the week. As behaviors occur,...

In this anatomy worksheet, students complete 22 review questions in the format of short answer, table completion, and fill in the blank after finishing an online virtual experiment about the chemical and physical processes of digestion.

A broad sampling of material related to stars is covered here. You will want to review each question to see if it corresponds to your curriculum. The formatting is inconsistent, but easily corrected if you use the information to create...

For this word formation worksheet, students identify groups of words that belong to the same word family, create word families from a given word, and fill in sentences using words that come from the same word family. Students answer...

In this math worksheet, students graph the functions on parallel axes and observe the location of the slope point in relation to the x and y axes.

In this map worksheet, students use information from given topical maps and locate the maxima and solve one dimensional wave equations. This two-page worksheet contains four problems.

In this derivative worksheet, students solve functions, sketch the direction of the rate of change, and describe functions using polar coordinates. This two-page worksheet contains seven multi-step problems.

In this math worksheet, students describe the difference between a partial and an ordinary differential equation. They give examples of 1st, 2nd, and 3rd order differential equations. Students apply this information to predator/prey...

In this interval worksheet, students write a geometric series for the derivatives of a function. Students determine the values of x and where it may converge. This two-page worksheet contains five multi-step problems.

In this definite integral worksheet, students use substitution to simplify integrals. They find the values of the upper and lower points and interpret points found on a graph. Students solve this two-page worksheet.

In this differentiation worksheet, students determine the seconds of motion, identify the constant, and speed of movement. This two-page worksheet contains five multi-step problems.

In this distance worksheet, students determine the distance between two objects, find the average velocity of an object, and define instantaneous velocity. This two-page worksheet contains six two-step problems.
