Using the game as a practice tool will take some planning because mini-activities within each Planet aren't organized by content. For example, activities in one Planet may cover number sense, fractions, and angle measures. Spend some time playing the game to determine how to best use it. It might be best as a mid-year or end-of-year pre-assessment practice tool. The Math Facts option can easily be used for daily warm-up or practice. Kids should work individually, but they can share devices since the game accommodates multiple users.Continue reading Show less
The two main options for play are Math Facts and Planet mini-activities. In Math Facts, kids complete a set of grade-appropriate drills as quickly and accurately as possible. In Planet mini-activities, more than 30 levels are spread across five Planets. Kids work on a variety of skills and activities with different themes. A progress-tracking program shows kids' scores as percentiles and as percent correct. Kids are motivated to earn points and stars, which they can use to unlock new avatars. A condensed, free, Android version of the game covers content for grades 2-8.
Kids can use Middle School Math Planet to practice and build fluency in core math skills. Content areas include number sense, estimation, fractions and mixed numbers, decimals, geometry, multiplication, division, and more. The game features mini-activities within each Planet, and kids have to complete one level in a Planet to go to the next level. Scaffolding is implemented throughout the game, even within mini-activities. For example, in a number line mini-activity, the game starts out with each interval labeled. As kids progress, labels disappear and kids have to use visual clues and estimation. The game also features a Math Facts section, in which kids choose a specific topic and race to complete drills with both speed and accuracy. Hints and feedback for incorrect answers are lacking, but this is still a solid tool for practicing key math skills.
Key Standards Supported
Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
Find the volume of a right rectangular prism with fractional edge lengths by packing it with unit cubes of the appropriate unit fraction edge lengths, and show that the volume is the same as would be found by multiplying the edge lengths of the prism. Apply the formulas V = l w h and V = b h to find volumes of right rectangular prisms with fractional edge lengths in the context of solving real-world and mathematical problems.
Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.
Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. Apply these techniques in the context of solving real-world and mathematical problems.
Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
Describe the two-dimensional figures that result from slicing three- dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.
Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.
The Number System
Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. For example, interpret –3 > –7 as a statement that –3 is located to the right of –7 on a number line oriented from left to right.
Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.
