Common Core standards require students to be able to read numbers as base 10 models, in expanded form, and in word form. The expectation is that students can fluently read and understand these and apply them to mathematical concepts throughout the 4th and 5th grade NBT standards. This passage on the Olympics will help your students meet this standard. As students read this passage they will unlock fun and interesting facts by reading numbers in various forms and recording them in standard form. This passage is great for intervention blocks, early finishers, or math stations.
