Mangroves are a nursery for a variety salt-water organisms. Learners explore the mangrove ecosystem through audio, video, and/or images, to see the organisms that live in this environment and make food chains pertaining to this...

Bamboo, the fastest growing plant in the world, can grow up to 35 inches in one day! Pupils learn how plants historically have been classified and determine if these traits are appropriate to use in this 17th lesson of 20. They will also...

Of all invertebrates, insects by far are the most numerous. Scholars discuss invertebrates and then use a key to classify them. They see different examples and must describe features of each organism based upon the key. 

Pine needles are actually modified leaves. In the 16th installment of 20, young scientists explore plants. Through an analysis of leaves — shape, veins, and edges — pupils see how to classify plants based on structural features.

Bryophytes can grow in temperatures just above zero degrees. This 17th installment in a series of 20 introduces learners to the five groups of plants: algae, bryophytes, pteridophytes, gymnosperms, and angiosperms. Classes then explore...

Interestingly enough, movement is not a characteristic of living things. The first activity in a series of 20 introduces learners to the concepts of living versus non-living things and then focuses on biologists and what they study....

Sixth graders visualize different percentages as parts of a whole on visual images. They observe alterations of photographs, and models of circles, squares and sets. This incredibly detailed, eight-page plan leads you through everything...

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

Pupils work in pairs to investigate what it takes to prove that two triangles are similar. They work through various shortcuts to find which are enough to show a similarity relationship between the triangles. Small groups work with the...

Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

Comparing the movement of graphs geometrically when small changes are made to the parent function motivates this collaborative discussion on the transformations of functions to their various forms. Vertical and horizontal shifts due to...

Maximizing resources is essential to productivity. Class members complete an activity to show how math can help in the process. Using a piece of construction paper, learners construct a box with the maximum volume. Ultimately, they...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

Scholars take transformations from the second to the third dimension as they extend their thinking of transformations to include three-dimensional figures. They explore how to use matrices to represent compositions of...

Is this enough to show the two triangles are congruent? Small groups work through different combinations of constructing triangles from congruent parts to determine which combinations create only congruent triangles. Participants use the...

Does doubling mean everything doubles? Learners adjust the scale factor between two rectangles. Using the calculated measurements, pupils investigate the ratios between the lengths, perimeters, and areas of the rectangles.

Study velocity while examining graphical representations. As scholars work with the animation, they discover the effect the height of an incline has on the velocity of the biker. They make conclusions about the slope of the...

Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

Basketball and math go hand in hand, even before one considers creating statistics. Viewers see a basketball player attempt multiple shots, but they do not see whether it goes in. They solve for which shots earned points as well as which...

Hard boiled or raw? Which egg will you get? A hands-on activity has scholars explore the impact of conditional probability. Based on a skit from the Tonight Show, pupils model the selection of the two types of eggs using beads. They...

This crossword puzzle is all about eggs! Learners use the given clues to fill in the squares in the puzzle. Since this is an online interactive resource, immediate feedback is available; although it only tells you whether you are wrong...

Learners use, with increasing confidence, problem-solving approaches to investigate and explain mathematical content. They make and test conjectures. They use tables and graphs as tools to interpret expressions, equations, and inequalities.

Here is an Alice in Wonderland word search puzzle where learners locate and circle 20 key terms and characters from the novel. Offer this to pupils who finish their work early, or who like to work puzzles at home. 

Introduce your class to words for groups of animals and people. This is a crossword puzzle that includes 25 clues for collective nouns. The puzzle is online interactive and learners can receive immediate online feedback. Answers are not...
