Today we explored how mountains erode over time. We used sugar cubes to represent the rocks and examined how they deteriorated after continuous shaking in a jar...similar to a rock tumbling down a mountain. We're getting closer to solving the mystery of the baby rhinoceros fossils found in Nebraska!

Ms. Katie Jo helped us review for our Unit 4 math test with a fun round of trivia. We worked with our teams to come up with answers and learned from mistakes. We were good sports and can't wait to try more. Check out the slideshow below if you want to review some of our math concepts at home. Ask us the difference between partitioned rectangle and partial products multiplication.

We've been diligently doing our spelling in book club each day. This week we're learning about three different spellings for the long u sound. By learning these patterns, we can predict the most common spellings for the words we write. Long u is spelled u-consonant-e when u is in the initial or medial position of a one syllable base word or in the final syllable of a longer word, as in mute and reuse. Long u is spelled u at the end of a syllable in a multisyllabic word, as in music. Long u is spelled ue in the final position, as in true and rescue. It's a lot of work, but our spelling is improving!

We're collaborating with Ms. Moran in STEM to compete in a contest called ExploraVision. We'll identify a global problem, look at existing solutions, do some research, create our own invention to solve the problem in an even better way, and document our work on a website. On Friday, we kicked it off with the whole fourth grade in the library. Now we can't wait to get started!
