]]>Here are five pieces of digital content a teacher might choose from StarrMatica’s library to support and enhance the teaching of: CCSS.MATH.CONTENT.5.MD.C.4 *Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.*

Students learn the meaning of volume and how to calculate it with cubes and numbers.

Students find the volume of a rectangular prism using cubes with the help of an animation.

Students create a cube with a chosen width, depth, and height. They can then reveal or hide its volume.

Use this isometric drawing tool to create shapes with different volumes.

Students use calculation to find the volume of food boxes for animals.

Here are five pieces of digital content a teacher might choose from StarrMatica’s library to support and enhance the teaching of: CCSS.MATH.CONTENT.4.OA.C.5 *Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3″ and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.*

Students learn how to find the core of a pattern and how to solve, shape, picture, symbol, and number patterns with this animated tutorial.

Challenge yourself to complete each pattern of numbers or shapes.

Students learn how to identify and extend a number pattern with an interactive tutorial.

Students use their number pattern know-how to crack the Mission 2110 codes.

Help Digit open the safe by choosing the correct number, color and shape to continue the pattern.

]]>**Place Value Game**

Students are challenged to create the largest number possible, yet once they place a number they aren’t able to move it. This causes them to think ahead about possible future digits.
