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 product is designed to help your students practice this skill while reading high interest reading passages. As students read these passages 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! The product includes 4 different passages that vary in difficulty. Topics include the Statue of Liberty, Olympic History, Orca Whales, and King Tut.
