###### Pros

Interactive games with minimal reading make activities accessible to a range of learners.###### Cons

Some visuals might be too childish for older students.###### Bottom Line

Great tool for differentiating in-class and at-home math practice.Teachers have full-featured control of which lessons each student can access as well as detailed statistics and reports about student mastery and progress.

Interactive games will captivate young kids to the point that they could become fully engrossed in the learning. The fun games and visuals are perfectly suited to the target age group.

Some of the games appropriately use rote memorization to teach the simplest concepts, but the biggest strength of this system is the simulation-type games that encourage kids to play with variables and observe the results.

Adults and kids alike will find lots support through instructions and screenshots from actual games and activities. Some wording might be difficult for struggling readers, but the games themselves are largely self-explanatory.

Because of the lack of teacher involvement when students are using ST Math: K-5, I recommend using it as a way to differentiate for different needs. Students who achieve mastery early can move on to more challenging concepts, and those who need extra help can get it from the teacher in a one-on-one or small-group setting.

The relatively simple technology requirements of this tool also make it great for homework assignments. Parents can monitor students and even participate in the interactive games.

Read More Read LessST Math: K-5 is a standards-linked collection of games and activities (via website or Chrome app) that teach and reinforce elementary-level math concepts using a visual method of instruction. Every major component of the K-5 Common Core math curriculum is covered, with a focus on arithmetic, geometry, and measurement. The activities are visual and interactive, with a focus on teaching math without language. In the various games and activities, students learn concepts by moving objects in a spatial-temporal way (hence the "ST" in its name). Students log in and choose a topic, and a colorful full-screen animation takes over to demonstrate what they need to do.

Read More Read LessWhen necessary, the games are designed to reinforce rote memorization, but most of the content revolves around students making choices and seeing the outcome. In one game, for example, students place birds on a telephone wire to discover how addition and subtraction work. This is a powerful way to explore mathematical concepts, and the lessons are well-designed and well-implemented. The absence of language makes this a great tool for those who struggle with reading, including kids with learning differences and English learners. Teachers can assign students individual lessons or the entire program, but this tool is probably best used to reinforce ideas after in-class instruction.

Students can see their progress in the games via easy-to-understand visuals, and the activities follow a progression that continues to challenge students as they hone their skills. For example, double-digit addition follows single-digit as they demonstrate mastery.

## Counting And Cardinality | |

K.CC: Count To Tell The Number Of Objects. | |

K.CC.4 | Understand the relationship between numbers and quantities; connect counting to cardinality. |

## Geometry | |

1.G: Reason With Shapes And Their Attributes. | |

1.G.1 | Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes. |

2.G: Reason With Shapes And Their Attributes. | |

2.G.1 | Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.5 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. |

3.G: Reason With Shapes And Their Attributes. | |

3.G.1 | Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories. |

4.G: Draw And Identify Lines And Angles, And Classify Shapes By Properties Of Their Lines And Angles. | |

4.G.2 | Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles. |

5.G: Graph Points On The Coordinate Plane To Solve Real-World And Mathematical Problems. | |

5.G.2 | Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation. |

K.G: Identify And Describe Shapes (Squares, Circles, Triangles, Rectangles, Hexagons, Cubes, Cones, Cylinders, And Spheres). | |

K.G.3 | Identify shapes as two-dimensional (lying in a plane, “flat”) or three- dimensional (“solid”). |

## Measurement And Data | |

1.MD: Measure Lengths Indirectly And By Iterating Length Units. | |

1.MD.1 | Order three objects by length; compare the lengths of two objects indirectly by using a third object. |

Tell And Write Time. | |

1.MD.3 | Tell and write time in hours and half-hours using analog and digital clocks. |

2.MD: Measure And Estimate Lengths In Standard Units. | |

2.MD.1 | Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. |

Work With Time And Money. | |

2.MD.7 | Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m. |

3.MD: Geometric Measurement: Understand Concepts Of Area And Relate Area To Multiplication And To Addition. | |

3.MD.5 | Recognize area as an attribute of plane figures and understand concepts of area measurement. |

Solve Problems Involving Measurement And Estimation Of Intervals Of Time, Liquid Volumes, And Masses Of Objects. | |

3.MD.1 | Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram. |

4.MD: Geometric Measurement: Understand Concepts Of Angle And Measure Angles. | |

4.MD.5.a | An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles. |

Solve Problems Involving Measurement And Conversion Of Measurements From A Larger Unit To A Smaller Unit. | |

4.MD.1 | Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two- column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ... |

5.MD: Convert Like Measurement Units Within A Given Measurement System. | |

5.MD.1 | Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems. |
