This is a twist on the old "guess how many jellybeans" game. Using estimation and math skills, learners participate in a fun "mystery jars" activity, trying to make educated guesses at how many objects are in two jars. The basic activity...

The number of craters on the surface of solar system objects has a direct correlation to its age. Learners use the concept to determine the age of several objects in the solar system. Using satellite images, they count craters within a...

Youngsters discover ways to estimate. They will use two jars with large and small items and estimate the number of items. Then record their estimate and explain why they answered the way they did. They try this experiment with different...

Discover how combinations are different from permutations. In the third installment of a 21-part module, scholars learn how to determine combinations of objects. They learn to distinguish between situations where order is important and...

Ready to have an "unforgettable" time in science class? Try a fun and insightful activity, suitable for a wide age group of learners. Explore how human memory works when pupils try to remember objects they've seen before comparing the...

Budding mathematicians explore the concept of skip counting. They practice skip counting as they use it to determine the number of wheels that come to school at 3 different times throughout the day. They also create a data graph to show...

The object is to model fraction division by asking “How many are in one group?” It is a difficult concept to understand, but developing the model that shows one cup to a certain amount of container or one container to a certain amount of...

Learners create a pictograph showing household size for the class.In this data collection and graphing lesson, the teacher guides students through the creation of a concrete object graph, then learners analyze and summarize the results.

Writing can become one-dimensional if authors don't involve all their senses. First, scholars observe a strange object which, ideally, they can touch and even smell. Without using certain words (you can create a list or have the class...

Students sort and count objects. In this sorting skills lesson, students work in small group with various objects that can be sorted and counted in groups.

Learners discuss the kinds of things they count and how to use tally marks. In this social science lesson, students count animal crackers by using tally marks for each kind of animal. The tally marks are changed into numbers and one...

Learners learn how to count animal populations by the Mark and Recapture method. In this counting animal populations lesson plan, students begin by predicting amounts of different candies in a jar. Learners then simulate using beans, two...

Students move around a makeshift "track" set up by the teacher, moving around it as many times as they can before the stop signal. Students begin by power walking and slow-jogging, then build up speed as they proceed. Students call out...

How do we compare? Get your scholars measuring using this interactive and kinesthetic math activity. First, learners compare something (you announce- could be index finger, palm, feet, etc.) to classmates. Consider having them record...

Work together to stay afloat. Using a paper boat, pupils connect properties of materials to their usefulness. They test different paper to determine how many pennies each boat will hold and learn that combining materials with different...

Seventh graders explore random sampling by estimating the number of e's on the newspaper. They explain the possible error sources for this type of sampling, and compare the accuracy of sampling a small and large population. This is a...

Students discover early number concepts for numbers 1 through 5. In this number concepts lesson, students work in stations doing hands-on activities such as sorting colored blocks, stringing beads, and counting sticks. Students also...

Students determine how many number cards are needed to display the dates of the month. In this place value notation lesson, students write numbers on blank cards to see how many are needed of each number to makes all the dates...

First graders work in cooperative groups and utilize a variety of materials to test objects ability to sink or float. In this sink or float lesson, 1st graders discover why some object sink and others float. Students will graph results...

Students predict the measurement of objects. For this measurement lesson, students estimate the measurements of objects in a lab. Students measure irregular objects and generate scientific observations.

Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

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...

How many visual models can be used to show multiplication? Three basic kinds of models can be used to represent and explain the equation 4 x (9 + 2).  The commentary section provides description and graphics to explain the set...
