With all the discussions on how recognizing number patterns when problem-solving is important, I hereby declare that yes, solving a problem requires recognizing number patterns, just like what I did for the past few problem activities.
If you see a pattern when you look systematically at specific examples, you can use that pattern to generalize what you see into a broader solution to a problem.
Here is a video that may be of help. It talks about patterns in fractions.
Here is also a link that talks a little on patterns.
At the end of the day, it is all about encouraging our little ones to recognize patterns, thick critically and solve problems. Feeding them with the answers will not help. Communicate why patterns work.
