In math this week, we started work on multiplication concepts. After our initial brainstorming in groups last week, we discussed in more depth what multiplication was, vocabulary associated with multiplication, and different strategies they knew to solve multiplication facts. In grade 4, students should be able to recall multiplication and related division facts to 7 x 7. They should also be able to understand and apply strategies for multiplication and related division facts to 9 × 9. We played the multiplication games “Closest to 20” and "Closest to 50" to practice and reinforce their basic facts. Students also worked on a multiplication booklet that was good review of the work from previous years in terms of arrays, relating multiplication to addition, and skip counting. Over the next few weeks, we will be learning and practicing different mental math strategies to determine basic multiplication facts to 9 x 9, and working up to 3-digit by 1-digit multiplication to solve problems. In science, students wrote their “Light & Shadows” test on Tuesday. The test will go home next week in their assessment duo tang for a parent signature. Students started work on our new science unit “Wheels and Levers” by doing some initial research using interactive sites about the six main simple machines, which include the lever, the wheel & axle, the pulley, the inclined plane, the wedge, and the screw. Students learned that simple machines make our work much easier, and were able to get an initial understanding of how these simple machines assist us in our everyday lives. We also watched an informative video called “All About Simple Machines.” Some things we learned from the video are that simple machines help us use less force to move things, and they have very few moving parts or no moving parts at all. In the coming weeks, we will be looking at each of these simple machines in more detail through experiments and hands-on activities.
Stay warm this weekend! —Ms. Jagger
