Students begin to formalize their understanding of probability. They are introduced to the concept of probability as a measure of likelihood and how to calculate probability as a ratio. The terms discussed (impossible, certain, etc.) in Lesson 1 are given numerical values.Key ConceptsStudents will think of probability as a ratio; it can be written as a fraction, decimal, or a percent ranging from 0 to 1.Students will think about ratio and proportion to predict results.Goals and Learning ObjectivesDefine probability as a measure of likelihood and the ratio of favorable outcomes to the total number of outcomes for an event.Predict results based on theoretical probability using ratio and proportion.

This is a set of three, one-page problems about the size and area of solar panels used to generate power. Learners will calculate area fractions to compare the sizes and distances of Jupiter's moons. Options are presented so that students may learn about the Juno mission through a NASA press release or about how solar energy is used by various NASA satellites and technology by viewing a NASA eClips video [3 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.

CK-12 Foundation's Middle School Math Grade 6 Flexbook covers the fundamentals of fractions, decimals, and geometry. Also explored are units of measurement, graphing concepts, and strategies for utilizing the book's content in practical situations.

This lesson follows the gradual release framework. It contains a teacher model, guided practice, and 2 independent student tasks. It walks students through the processing steps of the standard and helps them connect change unknown to the part-part-whole strategy. The teacher can add/tweak the slides to meet the needs of his/her students. 

Using a blank Kidbots grid, students should try to move the bot a particular shape.

This short video and interactive assessment activity is designed to teach fourth graders about comparing using greater than, less than, and equal to.

This short video and interactive assessment activity is designed to teach fourth graders about multiplying and dividing - missing operation.

This is an activity about the solar cycle. Learners will use X-ray data from the Geostationary Operational Environmental Satellite (GOES) and record the total number of solar flares in their birth month over the course of eleven years and compute the percentage of high-energy X-ray flares which occur for each year. Learners will graph their findings to help them identify the long term pattern of flare activity on the Sun.

Students will practice measuring the diameter and radius of food themed circular objects. Next, they will discover that finding the ratio of circumference and diameter is the value of approximately 3.14 or pi.
Then, using the number 3.14 for Pi, students will find the area of the various circular objects.

Students will practice measuring the diameter and radius of various circular objects. Next, they will discover the ratio of pi to about 3.
Then, using the number 3.14 for Pi, students will find the area of the various circular objects.

Touching and having cards with a number on each makes working with number order and rote counting more engaging.  

This short video and interactive assessment activity is designed to give fourth graders an overview of conversion among units of measure for capacity (english units).

Did you know that kids can program Ozobots with markers? Guide them through this fun discovery while reviewing geometric shapes!

Adults use computers for important things like banking, writing school reports, and communicating with each other. If the information being stored got changed without anyone knowing, you'd get the wrong balance in your account (too much or too little), the wrong grade in your report, or the wrong message in an email. Or worst still the website you are wanting to go to for your learning or the DVD you want to play won’t work! This activity will look at how computers correct this automatically.

Students identify angle measurements as part of a larger angle. Students will deconstruct 180 degree angles into equal parts.
