Today on Math Out Loud, we’ll focus on the word evaluate, e-v-a-l-u-a-t-e. The word evaluate is used in science and in everyday life but we’ll focus on the way we use it in math. The first time the word evaluate was used in a mathematical context was in 1842 in a Physics book by William Grove. Evaluate means to find the value of a numeric or algebraic expression. In other words, it means to solve or work out a value. An example of evaluate is 4 + 3 = 7 or 105 + 5 = 110. A non-example is giving up and not working out the problem. We’re the Math Masters with the word story of evaluate on Math Out Loud!

I love your non-example on this one! Giving up is definitely not evaluating. Giving your readers examples and non-examples is incredibly helpful. They will be much more likely to remember your vocabulary terms and definitions when they have examples and non-examples. Nice job, 6th grade.

Students I am so proud of you!!!! I have listened to each of your math outloud stories and my heart is just bubbling over with the degree of learning that is happening in your math class. I am sure the history about this vocabulary has made the content more meaningful and exciting to you. I encourage you to keep working on the math outloud to enuciate, be reflective about the meaning of each definition and then apply that learning to class each day! Go Roadrunners!!!
