Students took their Scientific Method Tests. We continue with Lifeboats tomorrow!
0 Comments
Today we took our models to the algorithm (process to solve). We took notes and practiced solving multiplication problems involving one decimal and one whole number. Students worked on pages 393-394 from their books. If at home more practiced is desired, IXL skills I3 and I4 from grade-level 5 is available.
Homework tonight: page 395-396- MUST SHOW WORK using Traditional Method **some students have an alternate assignment, but must also show work. Today we continued to work on multiplying. We used models to show how to get the products when multiplying whole numbers and decimals. We discussed how, for example, when multiplying 2 times 0.4 that two groups of 4 tenths would be 8 tenths and how this is the same math fact as if they were whole numbers that just have a decimal with it. Students did a great job in class and were able to use the patterns that they saw to apply them to new problems.
Homework tonight: page 389-390, and page 395 numbers 1-6 ONLY Today we continued our work with our lifeboats. Students used syringes and graduated cylinders to find the capacity of each lifeboat. Then they continued the trials to find out how many passengers could fit into each lifeboat without sinking. Homework: scientific method test tomorrow Today students worked on using their understanding of rounding numbers (decimals and whole numbers) to estimate products. This is very similar to what we did last month with just whole numbers. From here we will be moving into multiplying decimals.
Homework tonight: page 383-384 (students MUST show rounded numbers on problems 1-14) See example in notes picture Students took a quiz on identifying variables. They needed to distinguish between the different types of variables (manipulated, responding and controlled) and then apply that knowledge to be able to identify each variable in a given experiment scenario. This is a skill that we have worked on daily for the last three weeks.
Students also worked to write up a formal lab report from one of the flippers experiments (either flip stick length or angle of the base). They are using the data collected and information from their science notebooks to complete the lab report. We reviewed the format and I shared with students a document to help them with what should be in each section of their lab report. Homework: Scientific Method Test on Thursday Students are working on planning a family meal using flyers from local supermarkets. They have been given a budget of $100 (for a minimum of 10 people) and a list of required items. The class has done a nice job searching out deals (some using coupons!) to fill their Thanksgiving table. Final products will be added tomorrow :) We finished up our experiment trials for our Flippers unit by testing out the affect of flip stick length on the projectile height and the affect of the angle of the base on the projectile distance. Each of these experiments were conducted by the students in small groups. They had to use our class generated conclusion as a model for their own conclusions on these experiments. Next week, students will chose one of the above experiments to write up as a formal lab report, which will include a graph of their data. On Thursday some students continued to study/practice the addition/subtraction skills needed for the Chapter 5 test and others chose to take the test. Students who did not test on Thursday, tested on Friday. Those who had already finished their tests walked around the school surveying people about their favorite Thanksgiving pies. They then converted their tallied data into fractions, decimals and percents. After they completed their math work, they went online and input their data on the site "Create A Graph" and printed pie graphs of their survey results. Pictures to follow as soon as they are printed!
NEXT WEEK: we will be doing a Thanksgiving meal decimal activity. We need as many flyers as possible from grocery stores/food stores (ex: Shaws, Hannaford, Whole Foods, Trader Joes, Market Basket, Walmart, Target, CVS, Rite Aid) to use for our activity. Please consider sending in any that you have :) Today we co-wrote our conclusions for the first flippers experiment. Students have this in their science notebooks and will use the format when they independently write their conclusion for the next two flippers experiments.
