Examine the consequences of varying speed.  An engaging set of five problem sets challenges young mathematicians by targeting a different grade level from K-12. In the initial lesson, scholars make conclusions about the time it...

Cut-and-paste a great activity into your lesson plans. Scholars analyze real-world problems involving proportions. To change things up a bit they cut-and-paste quantities to create a proportion on their way to solving the problems.

Collaboration is the key for this equation-solving lesson. Learners solve a multi-step linear equation that requires using the distributive property. Within collaborative groups, scholars discuss multiple methods and troubleshoot mistakes.

Don't tire of solving equations, mix up your lesson! A virtual interactive has users drag paper tires to toy cars. Solving a one-step equation lets them find how many cars can be made from a given number of tires.

Here's an interactive that complements your lesson plans. Users of the resource adjust one of the angles in a complementary set to see how it affects the other. A set of challenge questions assesses understanding.

Pair up this resource with a lesson on linear pairs. Scholars solve for missing variables and values of angles in linear pairs. They use an interactive to help with this endeavor.

Reinforce properties while solving equations. Learners often ignore properties even as they try to apply them. A well-designed lesson emphasizes the role of additive inverses when solving equations.

Demonstrate the ease of using a frequency table. An interactive lesson allows learners to create a frequency table efficiently. Challenge questions ask your classes to analyze the data represented in the frequency table. 

You don't need to tip-toe around an enlightening resource. Young environmentalists learn about ecological footprints in the fourth lesson plan of 15. Answering a questionnaire helps them see how their own families and homes affect the...

Be sure you have enough money to build a house. The 14th lesson in a 15-part series teaches young learners to use checkbook registers. They write checks for the amounts they spend on various housing materials and keep track of...
