The hunt is on! Young mathematicians follow clues and complete a series of ten math puzzles as they try to crack Dr. Integer's code and find the location of his hidden treasure.

The phonemic awareness activities in this packet are designed to help kids develop skills in rhyming, syllabication, blending onsets and rimes, and beginning and ending sounds. Well worth a place in your curriculum library.

Everything you wanted to know about calculus—and more! The resource is a complete Calculus textbook with explanations, examples, and practice problems. 

Where can you see an aurora in North America? After completing an astronomy activity, scholars can locate the exact coordinates. Pupils plot points of the inner and outer ring of the auroral oval and answer questions based on...

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Introduce learners to set of complete instructions that describe how to build a magnetometer that works just like the ones professional photographers use to predict auroras. The diagrams are wonderfully descriptive, and the written...

Young scholars explore the concept of coordinate proofs. In this coordinate proofs lesson, students write coordinate proofs using properties of distance, slope, and midpoint. Young scholars discuss why it is sometimes beneficial to...

Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs. Students give examples of concentric, similar, and congruent circles and congruent arcs.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Students explore the relationships between similar figures. In this relationships between similar figures lesson, students discuss relationships between perimeter, circumference, area, surface area, and volume of similar figures through...
