Students investigate positive and negative numbers using lima beans as a concrete model.

Eighth graders collect data from Bottle Biology compost columns and record using Excel spreadsheet.

Students measure distances and report them in fractions, convert fractions to decimals, and multiply decimals.

Students arrive at a verifiable rule, or set of rules, to handle all addition situations with signed numbers.

Ninth graders investigate the finding of the diameter of a circle in order to extend the practice towards finding the circumference. They differentiate between the distance measured across a circle from that of around the perimeter.

Students use a variety of strategies to figure out the cost of baseball tickets. They use a combination chart, notebook notation, etc. to find the cost of their family to attend a Cardinal's game in St. Louis.

Students manipulate negative and positive numbers. In this integers lesson, students move through three activities exploring negative and positive whole numbers. A number line, cardboard function representation, and solving expressions...

Eighth graders determine whether given fractions can be reduced, and if so, complete the reduction. They write in their Math Journals on the prompt "What does it mean to count something?"

Students solve problems involving exponents. Through a teacher led discussion, students explore the rules of exponents and create cards with "x's" on them. Given a division problem, students lay out "x's" to represent the numerator and...

Students engage in a lesson that is concerned with the concepts related to probability. They review the key properties of statistics involved in the measurement of probability that includes mean, median, and mode. The lesson includes...

Students evaluate squares and square roots. Through practice, they discover the inverse relationship between squares and square roots. Students take notes, solve square root and square root problems, and classify numbers as rational or...

Eighth graders practice using the LIST key on graphing calculators using the proper syntax. They work with the functions of mean, median, and mode in a teacher led lesson and then with a partner on a second data set. They follow...

Eighth graders extend skills for representing and solving linear equations to linear inequalities. Lesson activities build understanding and skill by plotting ordered pairs of numbers that either satisfy or do not satisfy a given...

Students solve systems of 2-by-2 linear equations using tables, graphs and substitution. In small groups, classmates work together to discover strategies for solving equations. They use a calculator to graphically represent their answers.

Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.

Students build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Students sort objects based on one characteristic. They define the term "attribute" and give examples of attributes of objects. Students explain their reasoning for sorting objects into groups.

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

Students explore the graphing calculator feature on the Macintosh computer to explore some "parent" functions and their translations, combinations, and composites.

Tenth graders investigate three different sets of data that relate temperature to another variable in the physical world. These illustrate linear, inverse and exponential relationships.

Young scholars become "shape detectives" as they identify, name, create and describe common shapes within pictures and objects found within the learning environment. Suggestions include incorporating shapes into all learning areas and...

What did you do over your summer vacation. Young wage earners must compare summer job options, and determine when each job earn the same amount and what that amount be. This be done by creating, graphing, and solving systems of...

First graders investigate the Commutative Property of Addition. It is introduced using models such as students, counters, balances and dominoes. They discover the order of the numbers in an addition sentence does not change the result...

Young scholars review the characteristics of wetlands and list their benefits. After viewing short videos, they identify the organims that make their home in wetlands and how they have adapted. They compare and contrast the...
