Sophia: Converting Between Square Miles and Square Kilometers: Lesson 2

Root for your pupils to learn about roots. Young mathematicians first review the meaning of squares and square roots. They then use this knowledge to simplify square roots of monomials with variables.

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Gain practice converting between metric units of volume and mass. The class goes over the procedures for making the conversions as a whole. The strategy used here includes making charts that show the relationships between the...

A great resource for any math teacher covering multiples, factors or square roots; this worksheet walks young mathematicians through the logic behind factoring and square roots with a systematic set of problems which gradually increase...

Math scholars with a basic grasp on units of measure will appreciate this video. Sal breaks down the process needed to convert between metric units. He defines kilo, hecto, and deka than uses that framework to assist him in determining...

Practice is an important learning tool. This practice problem allows students to apply their know-how to factoring a binomial with a difference of squares. Sal explains his process briefly, which makes this video appropriate for those...

Though Sal expects viewers to be "reasonably familiar" with square roots, he takes this opportunity to explain some of the notation and how to graph square root functions. He uses a graphing calculator from my.hrw.com/math06 to...

Provide your students with the context and information they'll need to convert gallons to quarts, pint, and cups. In this video, Sal defines gallons, quarts, pints, and cups. Then he uses this information to solve a problem where he must...

Think outside the box and use an engaging, interactive app that shows the relationship between square roots and squares using an actual square. Pupils find that moving a slider increases the side length of a square and its associated area.

Manipulatives make learning division easier! Your class will discover the difference between dividing with one- and two-digit divisors, and practice the procedures for each using the standard algorithm. They will use estimation to ensure...
