Sophia: Terms Relating to Solids

Connect the tortoise and the hare fable to mathematics. Learners first identify key terms related to distance, rate, and time. They then solve distance/rate/time problems using different representations.

Test your pupils' reasoning skills with several activities and a quick mystery to solve. Learners watch and analyze a few video clips that demonstrate reasoning in action, practice deduction with an interactive and collaborative...

See how linear relations relate to functions. Viewers of a short video learn to write linear relations in functional form. Given a linear equation in standard form, they isolate one of the variables to rewrite it in terms of the other...

Math has a language all its own. A well-designed video explains the mathematical language related to equations and formulas. The instructor uses common language to describe the symbols and operations people expect to see when working...

Here's everything you need to know about algebraic expressions in 10 minutes or less! From an introduction to vocabulary to simplifying with the distributive property, the video lesson has a little bit of everything related to...

Discover the pattern of exponents through an interactive lesson. Young mathematicians manipulate sliders and watch the result as they change the base or exponents in an expression. The tutorial shows them the simplified expression and...

Let's move into the third dimension! Learners explore the vocabulary and notation related to three-dimensional figures. The video covers examples of pyramids, but the vocabulary is universal to all 3-D objects.

Functions are special relations, but are there special functions? A concept video defines a one-to-one function. Three problem videos cover examples in determining whether a relation is a function and whether it is a one-to-one...

Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...

Students learn about the terms related to logic and conditional statements. Terms explored are conditional, contrapositive, inverse, converse, and biconditional.
