Place Value Perfection

Place value and estimation is where we start our third grade math standards.  We have studying numbers and the place value patterns under 1 million for the last month.  If you are following us on SeeSaw I'm sure you have seen all the place value posts. We explored reading and writing numbers in standard form, base ten models, written form, and expanded form. We also learned important vocabulary like place, digit, value, and estimate. Exploring place value and developing number sense is foundational to all math concepts.  We practiced these concepts through games, paper pencil activities, iPad apps, whiteboard practice, and rich math discussions.

If you want some extra activities to play at home, check out Math Slides.  There is a great place value version and one called numbers >1000.  Another great app is called Mystery Number.  It is similar to this the number riddle games we have been playing in class.  The app contains four different games that give students lots of opportunities to explore concepts of number and place value. The games can be played with one player or two.  Check out Mystery Number ($1.99) on the app store.
