Young mathematicians use fraction names and symbols to describe fractional parts of whole objects or sets of objects. They construct concrete models of fractions, and compare fractional parts of whole objects in a problem situation using...

Kindergarteners put Cheerios or cheddar fish on two number lines (up to 10 each) and identify which number the snack pieces indicate. They compare numbers after eating a few of each snack, and get an introduction to addition and...

Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

Linear measurement is the focus of this math instructional activity. Youngsters work in groups to build towers with blocks. They build towers represented on index cards and determine how many blocks taller one tower is.

You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

Engage your mathematicians with this simple number-quantity game. Working in pairs, using two decks of 44 cards numbered 0-10 with corresponding sets of objects or images, young learners will each flip a card and decide...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Help mathematicians estimate how many seeds are in a given vegetable or fruit. They are divided into pairs and estimate the amount of seeds in a whole fruit without seeing the inside. They then cut the fruit or vegetable in half and...

Here is an excellent lesson for young learners who are just beginning to explore the concept of using units to measure length. They rotate through four classroom centers in order to gain practice in utilizing this important skill.

As amazing as James Bond is, the surface tension of water does not allow him to walk on it! In this series of little lab activities, physical scientists play with the properties of water due to the hydrogen bonds and resulting polarity....

Review the difference between rocks and minerals using this resource. Learners identify and investigate the physical properties of these objects. They create a Venn diagram to compare and contrast types of rocks. This is a motivating way...

Take advantage of this interdisciplinary resource and bring together topics in science, language arts, and math. Use characters and events from the story Tillena Lou's Big Adventure as a context for practicing addition and...

Students practice counting and comparing objects.  In this math lesson, students view a Count on It! episode. Students examine the value of what they are counting.  Students estimate number in groups of items.  Students...

Visit the Magic Treehouse and take your class on a trip through time with a reading of the children's book Mummies in the Morning. Using the story to spark an investigation into Egyptian culture, this literature unit engages...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Hang out at the beach and listen to some relaxing tunes, all while developing basic math skills. An endless source of fun and learning for young children!

Harper Lee's To Kill a Mockingbird, considered by many to be a seminal piece of American literature, contains many complex literary themes that carry through United States history. Use a series of discussion questions and classroom...

It is positive that how one performs on the first test relates to their performance on the second test. The three-question assessment has class members read and analyze a scatter plot of test scores. They must determine whether...

Hands-on stations in which groups of primary learners experience what mirrors can do provide opportunities for experimenting and authentic discovery. Recording their observations in complete sentences seems age-inappropriate. Drawing...

Your learners practice writing ideas on paper and logically presenting them in an organized manner. They brainstorm ways to write down ideas while creating a travelogue about a particular U.S. geographic region. When they present...

Tiny mathematicians count the number of shapes (up to 8) in pairs of object groups and identify the sets as equal or not equal. Five practice problems. They also draw 2 groups of shapes that are not equal. A focused tool that...

Where do bananas, cats, stars, and flowers combine? In this number values worksheet! Learners examine sets of images and answer five questions comparing the number of certain objects to others. They use the math terms greater than,...

In this comparing weights worksheet, students observe sets of three objects and number them from lightest to heaviest. Students solve 9 problems.
