The Math patterns 1 exercise appears under the 3rd grade (U.S.) Math Mission. This exercise plays with patterns and prediction in mathematics.
Types of Problems
There are four types of problems in this exercise:
- Follow the pattern: This problem gives a sequence of numbers with a couple numbers missing and the rule that was followed to make the sequence. The user is supposed to fills in the missing spots with the correct numbers.
- Find the pattern: This problem displays a sequence of numbers. The user is supposed to determine the rule that made the pattern and selects the correct option from a given list.
- Complete the chart: This problem has a chart of inputs and outputs that create a predictable pattern. One entry is missing and users are asked to find it and put it in the correct spot.
- Type of sum: This problem asks which pairs of number create even or odd sums. Users are to select all such pairs from a multiple select list.
- For the first three types of problems, the patterns are all arithmetic (adding a common number) or geometric (multiplying by a common number).
- The rules for Type of sum are important enough to be mentioned: 1) the sum of two numbers of the same parity (even or odd) is always even and 2) the sum of two numbers of opposite parity is always odd.
- Since there are only three options on Type of sum it is really easiest to just add all the sets of numbers and see which work.
- Pattern recognition is a common skill on IQ tests.
