Math analogies in second grade? Absolutely! We have added a daily math analogy to our Calendar Math routine in the mornings to develop deeper critical thinking skills among our students and to expand their math vocabulary. An analogy is simply a way of looking at items and determining the type of comparison that is being made among them. At the beginning of the year, we start out very simple. Here is the first one we did in class:
one : 1 : : three : _____
When read aloud, a student would say, “One is to 1 as three is to blank.” Students would then look at the first part of the analogy.
How are one and 1 related? One is the word form of the number 1.
After students determine the relationship of the first part of the analogy, they use that information to help them determine what the answer to the analogy is.
Three is the word form of the number 3, which means one : 1 : : three : 3.
As the year progresses, our math analogies will get more difficult. Relationships between the two parts will not always be synonyms. Sometimes the relationships will be antonyms or parts of a whole. Students will have to determine the type of relationship first before being able to solve the analogy.
Here are several more samples for the beginning of the year:
Greater than : > : : Less than : _____
15, 25, 35 : 45 : : 11, 21, 31 : _____
1, 3, 5 : odd : : 2, 4, 6 : _____
