Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...

Small and large are relative terms; what's the best way to quantify them? Young scientists take on that challenge as they complete an interactive activity to explore size. They build structures during their exploration and begin using...

Just how big is Earth's moon? With a hands-on simulation, scholars use Play-Doh to model the sizes of the planets Earth, Mars, Jupiter, and their moons. They make predictions as a class, work together to make their models, and discuss...

Scholars gain an insight into the relative size of planets and distance between inner and outer planets with the help of informational text, a data table, and a series of four questions.  

Reinforce comparative adjectives and relative size with a drawing activity. Kindergartners study a thin house and a thin balloon, then draw a thinner version of each. They also choose the thinnest bottle and lollipop in a group. Focus on...

Do your kindergartners know the difference between thick and thin? After reviewing a picture of a tree and a candle, kids draw a thicker version of each in the space provided. They also draw a ring around the thickest pencil and the...

Reinforce relative size and following directions. After looking at a small bottle and flower, kindergartners draw a taller version of each in the circle provided. They then choose the tallest building out of five. Bring the lesson to...

Can your kindergartners draw a shorter tree? What about a shorter kite string? Reinforce relative size and comparing with a clever worksheet. It prompts young learners to study a picture and draw a shorter version, and to choose the...

This worm might be long, but can scholars draw an even longer worm? Focus on relative size as they draw a longer worm and then a longer necklace. Next, youngsters examine two sets of objects and check off the longest in an introduction...

Kids can estimate weight, length, and height. Here, they circle the measurement that best describes the length, height, or weight of 10 different objects. 

Students research the solar system and it's characteristics.  In this solar system lesson, students are broken into 4 groups, each assigned a specific part of the solar system.  Students use the Internet to research their part of the...

First graders compare triangle sizes, square sizes, and lengths. They use manipulatives of three varied sized triangles, squares, and strips to measure and compare relative size and length.
