Most volumes begin with an explanation of basic arithmetic operations namely: addition, subtraction, multiplication, and division. Reference tables are supplied to provide clues for quick mental arithmetic and mastery of math facts. When ready to be tested, the student can select a drill, which has 10 questions and are selected from a database of number pairs for calculation. The Basic Level volumes use simple single digit numbers and the interactive math software at the Advanced Level uses mostly double digit numbers for math practice problems. Each drill is then scored and timed with the results saved. With the test records, students can follow their own progress and adults who may be supervising can monitor progress and assess if there are any learning issues that require intervention.
The answer for the above question is hidden in a simple example. I always give the example of stairs to my students, and giving the same example in this article. I compare the steps of a staircase to the concepts in mathematics. As this is very hard to reach higher floors of a building without stairs (or elevators these days), same way learn higher concepts in mathematics without learning basic concepts is very hard. People have to start from the ground, then first step, second, third and so on to reach their destination floor. Exactly the same way students have to start from Kindergarten, then grade one, grade two and three and so on to reach their math destination. Also, if some of the steps are broken in the staircase, it is still hard to reach the desired floor using those steps. Same way, if you are missing some of the basic concepts from elementary grades, math for you is still hard.
By the time they are learning first grade math, kids should be ready to tackle things like the relationship between addition and subtraction, the concept of adding and subtracting two-digit numbers and learning to count beyond 100. Being able to compare numbers as larger, smaller or equal to each other is also important, as it provides the basis for recognizing whether or not the answer to a computation problem is the correct one. Children need to be allowed to master these and other essential math skills before being asked to move on to new ideas, but the modern classroom setting does not always allow for this. As focus on core curriculum begins to push complex ideas into lower grade levels, kids are expected to learn more at a younger age. First grade math still contains many fundamental concepts essential for understanding higher math, and therefore should not be rushed through. By letting a child try and re-try each new thing as it comes, online math games can give the extra time and practice that struggling students need to achieve success.
