3rd Grade Math Review: Day 3
In yesterday's post we looked at comparing and ordering numbers along with equivalent fractions on a number line. Today we finish the first reporting category (section) of the 3rd grade math curriculum, numerical representations and relationships, by looking at comparing fractions using pictorial representations, even and odd numbers, and more fractions on a number line.
Fractions at this point in students' education are still compared with pictorial representations rather than simply evaluating the numerators and denominators. The video below shows what this means for third graders.
With that reminder, try this practice problem from a released STAAR test.
Even and Odd
Students have learned about even and odd numbers starting in the first grade. In third grade, however, they begin to link those ideas with divisibility rules, something that will become more important in future years. Here's a refresher on that concept.
With that in mind, try this problem out to test your skill.
More Fractions on a Number Line
Discussed yesterday, fractions on a number line are a very important concept for third graders. Linking this idea to multiple representations is a sure way to help it solidify in students' brains. Here's another video showing exactly what that means.
Hopefully that video helped clarify a few things. Now try this problem from a released STAAR test.
Here are the answers and explanations. Make sure you've worked through the problems first before watching the video below.
