Patterns are everywhere! In this week-long learning adventure, children will discover what a pattern is and explore patterns in different ways. Children will learn that patterns consist of a "core" or "unit" that repeats as they identify...

Investigate dilations using this interactive resource. Students are given an opportunity to explore how scale factors can be used to enlarge or reduce the size of a given figure. Be sure to follow the link to the printable activities,...

Could the altitude of the city hosting the Olympic and Paralympic Games have an effect on performance in the long jump? This challenging activity encourages mathematical reflection, investigation and discussion as students explore how...

This activity investigates the importance of accurate measurement in competitive sport, looking at examples from athletics and swimming. It is aimed at secondary maths students (grades 8, 9, and 10).

This hands-on lesson discusses and explores rational numbers. Students construct personal fractional strip kits and use them to compare fractional amounts and investigate equivalence. The lesson plan includes instructions, materials, and...

Students will use their TI-84 Plus and Cabri Jr to investigate SSS triangle congruence.

In this activity, students will investigate the relationship among the three types of rigid transformations - translations, rotations, and reflections.

In this task, students investigate how many coins will fit around a central coin when they are all of the same denomination, and if there is room left over. The teacher is given a chart of four coin denominations and their diameters, but...

In this task, students investigate the volume of tennis balls and their cylindrical container, the empty space around the balls, different ways of slicing them, and what their visualizations will look like. Aligns with G-GMD.B.4 and...

In this task, students investigate why total solar eclipses are rare. They will learn that, in addition to requiring the positioning of the Sun, Moon, and Earth, the Moon can only completely block out the Sun when it is closest to the...

In this task, learners investigate the relationship between linear equations and linear functions. Aligns with F-LE.A.2.

In this task involving temperature conversions, learners construct a linear function given two input-output pairs, investigate the inverse of a linear function, and reason about quantities and/or solving a linear equation. Aligns with...

A lesson, practice exercise, and resource for use when planning classroom instruction on linear quadratic systems. Find definitions, example equations and graphs, a four-question quiz with solutions, and an activity through which...

Investigate how skeletal populations can help determine the impact of slavery on the height and health of African American males. This video focuses on the measurements and equations Mark Mack is using to explore relationships between...

Investigate some of the mathematical challenges Boston engineers had to deal with during the Central Artery Tunnel Project (the "Big Dig"). This video focuses on the irregular shape of the casting basin and the volume calculations...

The downloadable monograph investigates the electrification of Los Angeles. Topics include scientific principles associated with major technological advances in electrical power production.

A stem and leaf plot is a graphical representation for investigating variation. You will convert an ordered stem and leaf display grouped by tens into an ordered display grouped by fives.
