Exercise Name: | Math patterns 1 |
Math Missions: | 3rd grade (U.S.) Math Mission |
Types of Problems: | 4 |
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.
Strategies
This exercise is easy to get accuracy badges because the patterns are all pretty simple at this stage. Despite the different types of problems, the speed badges are also easy.
- 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.
Real-life Applications
- Pattern recognition is a common skill on IQ tests.
