Today we floated our "lifeboats"! Each group determined the number of pennies (passengers) that their boat could carry without sinking. We then averaged the data and graphed the results. We talked about drawing a conclusion from the data and providing evidence to make a strong argument. Our scientists did a great job today :)

We continued work on multiplying using the traditional method today. We reviewed homework (pages 135-136) and began an independent assignment that reviewed multiplication and exponents. This worksheet (P13/P14) is due on Tuesday, November 29th. We worked on finding the capacity of different sized "lifeboats" by filling them with water and using a syringe and a graduated cylinder to determine how many milliliters of water fit into each boat. Tomorrow we will be testing out the "lifeboats" to see how many "passengers" they can carry without sinking.
Today we worked on using the traditional method to multiply multi-digit numbers by a single-digit number. We went through several examples on the board and took notes on the procedure (see picture below).
Homework tonight: complete My Homework pages 135-136, students must do estimates on problems 1-4 before solving. We worked on solidifying using rounding and mental math to estimate products. Students wrote notes in their math notebooks with steps on how we did this (see pictures below).
Today we continued our discussion of buoyancy, and density. Students read in small groups an piece from our Variables science book on how to determine density. From that reading we discussed and developed definitions for the words buoyancy, density and volume (see picture below). Students recorded the definitions in their science notebooks.
Today we reviewed some changes in routine (not handing in homework before it has been reviewed, math message) and reviewed the last assignment that was done with Mrs. Ely. We discussed and practiced using rounding to be able to make mental product estimates (see pictures of notes below). One big idea discussed was to make estimates most accurate by rounding one factor up and the other down but that the numbers should always be compatible or easy to work with mentally.
Homework: Complete Homework page 229 (front side only tonight) We watched a video today introducing the concept of buoyancy and density and how they are related. Students took notes on how density of an object relates to its buoyancy.
Today students completed the Marshmallow Challenge! The winning tower in P4 was 24 inches tall! The winning tower in P8 was 30 inches tall! Great work, kids!! While this was originally an activity designed for project managers and executives, it has been adapted many times over due to its broad appeal. This activity gave students the opportunity to interact with engineering and design standards:
3-5-ETS1-2 Engineering Design: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.Performance Expectation 3-5-ETS1-3 Engineering Design: Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved. It also gave them practice with their teamwork skills such as positive communication, individual responsibility and accountability, constructive feedback, problem solving, organization and knowledge of roles. FMI check out: marshmallowchallenge.com/Instructions_files/TED2010_Tom_Wujec_Marshmallow_Challenge_Web_Version.pdf www.tomwujec.com/design-projects/marshmallow-challenge/ Today we finished Lesson 7, the Distributive Property. Students completed pages 121-122 in small groups in class.
Homework: workbook pgs. 123-124. (Some early finishers of pgs. 121-122 were able to start and/or finish their homework in class.) |
