Today students took their multiplication assessment. For many they used both the math and science blocks to complete the work. Some students will be coming home with a note in their planner about missing work that needs to be found or completed and turned in.

Today we talked about the variables that students found from their data collection yesterday. We identified which manipulated variable (amount of force) we will test and what responding variable (height) we are testing for. After that we discussed how we were going to control all of the other variables that they identified. We then tested out our systems to see where to place the bases in order to not create obstructions when collecting data. Today we reviewed how to use front-end rounding to make product estimates and then compare them to their actual answers. We practiced traditional multiplication in preparation for our multiplication test tomorrow.
HOMEWORK TONIGHT: HOME LINK 2-7- MUST SHOW WORK! MULTIPLICATION TEST TOMORROW! Today the Newtons started with 5 minutes to work on their conclusions (see picture below of expected parts). Everyone also finished the construction of their flipsticks by adding the length lines to long part of the stick. Students then worked in their groups to collected information about how the flipper systems, including a small and large tinfoil ball, worked. We will use this information tomorrow to develop a list of testable variables before getting started on our fair tests. Today we reviewed traditional multiplication and discussed the upcoming assessment (on Thursday). Our 5th grade target is to be able to solve 3-digit by 2-digit multiplication problems. After our quick review, students self-selected a sheet to work on (either 2-digit by 2-digit or 3-digit by 2-digit multiplication). Whatever they were not able to finish during the 30 minutes of work time needs to be completed for homework tonight.
HOMEWORK TONIGHT: "WINK OF AN EYE" (2-digit by 2-digit) "GOOSE EGG" (3-digit by 2-digit) MULTIPLICATION TEST ON THURSDAY Today we constructed our "flip sticks" in preparation for our next "fair test" investigation on "Flippers" which are catapult systems. Tomorrow we will be gathering information about how the flippers perform so that we can isolate some variables to test.
Students were given the remaining time to complete their Swingers Lab Reports. The Newtons did not have as much time and will be given 5 minutes at the start of class to finish up their reports. These will need to be done by the end of the week so that they can be printed and glued into STEM notebooks as exemplars for their future lab reports. Today we reviewed converting between units in the customary system. We focused on being able to identify if we were going from a big unit to a small unit (and to multiply) or a small unit to a big unit (we we would need to divide). We practiced several problems as a class then students were able to use calculators (and can on their homework if needed) to complete the conversion problems from a worksheet.
HOMEWORK TONIGHT: P84 WORKSHEET (MAY USE CALCULATOR, #8 IS A CHALLENGE PROBLEM) Today students logged in to Khan Academy Mappers. This is an online program through Khan Academy (think "how to videos" for math) that takes student NWEA scores and recommends skills that students can practice at their individual challenge level. This is a resource that we will utilize throughout the school year to push students during "free" time.
For most students their username is just their first and last name. A few (because they are more common names) have numbers also- these will be found in their planners. Passwords are all the same format the word cape (all lower case) followed by their lunch number. For example: cape12345. https://www.khanacademy.org/mappers Today we watched two short videos (What Ifs and Bowled Over) on variables and fair tests (isolating variables). Students took notes (see images below) and we connected the ideas back to the work that we did with our pendulums.
Today we worked on making product estimates by rounding to the biggest place (so that there was only one non-zero digit) and then multiplying the two non-zero numbers and placing all of the zeros behind that product. For example, if the factors were 27*43, you would round 27 to 30 and 43 to 40. Then multiply 3 by 4 to get 12 and place two zeros (one from 30 and one from 40) behind the 12 to get an estimate of 1,200.
We also talked a bit about estimating quotients (division) using compatible numbers which we will do later in this unit. The remaining time in class was given to practicing multi-digit (2 or more) multiplication using the online math book game "Top It". Students could choose from two challenge levels. All problems must include the rounded factors on their homework- see example below: Estimate the product of 27 and 43: Answer (required format) 30 * 40 = 1,200 HOMEWORK TONIGHT: ESTIMATING PRODUCTS SIDE IS REQUIRED, ESTIMATING QUOTIENTS IS A CHALLENGE AND NOT REQUIRED |
