Todo Number Matrix can be a fun part of any math curriculum, but it may be especially useful for kids who need a creative, visual approach to exploring math. Use the matrices as a reinforcement to challenge kids to put their logic and math skills to the test, or as an alternative way to introduce new concepts. Since there is no explicit teaching within the app, if teachers use these matrices for new concepts, they should play along and help explain the new material -- at least until kids get their bearing. Once they get the hang of it, let kids play on their own. Play gets more difficult with each level, but there's no option for creating multiple user accounts. Teachers should monitor kids so that they start at the level that's right for them, or let kids finish the whole cycle and then start over again with a new kid. Extend learning beyond the screen with hands-on math explorations in the classroom. Teachers could even construct a life-sized matrix and have kids move around within it, carrying cards to their correct slots.Continue reading Show less
In Todo Number Matrix, kids explore math concepts by figuring out the relationship between two images. Sixty-three matrices are organized by math topic: number, logic, shape, addition and subtraction, multiplication, and fractions. Each topic has multiple levels that get progressively more challenging. For example, number matrices start with figuring out that a picture of two apples should go at the intersection of two axes: the number two and a picture of an apple. A more advanced number matrix has a "shape" axis and a "6" axis, and kids must find the picture of a shape with six sides. Matrices start 2x2 and get bigger in higher levels. If kids need a hint, they can tap a question mark button to see where one picture should be placed. As kids complete levels, they collect badges on a progress chart; if they complete all 63 levels, they get a medal.
This thoughtful, unusual approach to exploring math concepts nicely taps into problem-solving capabilities. Kids need to have a good familiarity with numbers and also use critical-thinking skills to intuit the relationship between two images -- for example, that an apple and a number 2 equals two apples. This highly visual and logic-based approach to interacting with math may be especially helpful for kids who do not connect well with more traditional teaching methods. One downside is that there is no explicit guidance or instruction; instead, kids learn entirely through trial and error. Simply showing kids the solution –- which is what happens when kids tap the question mark for help –- may not be the best way to help them learn. A short how-to video or on-the-spot tutorials would be wonderful additions. Learning extensions would also help round out the experience and deepen learning potential.
Key Standards Supported
Counting And Cardinality
Compare two numbers between 1 and 10 presented as written numerals.
Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
Measurement And Data
Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.3
Operations And Algebraic Thinking
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
Represent addition and subtraction with objects, fingers, mental images, drawings2, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
