Today we worked with the metric system to convert units of length. Students practiced some multiplying with decimals to solve but quickly noticed a pattern that made it easier. We discovered that you can multiply by powers of 10 simply by moving the decimal to the left (dividing) or right (multiplying) based on the number of zeros in the number. For example, 1.234 x 10 would move to the right (multiplying) one place (one zero in the number 10) to be 12.34.

Today we worked on the first part of an Explore Learning Gizmo on the seasons. Students worked in partners going through several of the activities about how the seasons affect daylight and shadows.
Today we reviewed student practice on converting customary units of length and capacity. Students felt comfortable with the their work, so we moved onto converting customary units of weight (mass). Most students were flying through this and some got their homework done.
Homework tonight: page 829-830 Today we followed up on the lesson from yesterday with the questions about seasons and the length of the day. Students did a great job with being able to identify season based on details like length of shadows, amount of daylight, and time of sunrise and sunset. In my homeroom class (Arbours) we watched a video on study jams- the Newtons will watch this at the beginning of class tomorrow.
There will be a quiz on Friday on seasons, day/night, rotation and revolution. Today we practiced with two different strategies to convert between customary units. We worked with setting up ratios with the units and converting using either equivalent fractions or "cross-multiply and divide" method. We practiced with both units of length (review from Monday) and capacity (cups, pints...).
Homework tonight: page 843-844 Today we did a reading on seasons and day/night with a highlight on rotation/revolution and axial tilt. Students underlined as I read aloud and we used that to generate class discussion. This was largely a review from last week. We then began to answer a couple of questions based on the reading.
At the end of class, we watched a couple of videos (Mad Scientist, Hack the Festival) on the upcoming Festival of Curiosity. Students were given a sheet with the planned activities as well as a sheet to list their preference on certain high-interest sessions. These gold sheets need to be returned to school by next Monday, May 15th. Today we did a quick review of measuring to the nearest 1/2 and 1/4 inch. This took some reminders that each half-inch also includes the whole inches and similarly with the quarters (half and whole inches). We will continue to practice at the beginning of each math class to master this skill.
The primary focus of the lesson was on converting between customary units (inches/feet/yards/miles). We took notes on the conversions and did some practice. The most challenging part for students is remembering when to multiply and when to divide, so we took notes on that and discussed that when going from big units to small to multiply (getting more parts that are smaller) and the reverse of grouping lots of small parts into fewer big groups (by using division). Homework tonight: page 811-812 We did not have class today (or tomorrow) due to MEA science testing. We will resume our work on rotation and revolution on Thursday :)
Today we reviewed the work that students did yesterday on multiplying mixed numbers. Though there were some challenging problems on last night's homework, students really understand how to complete these problems. We also worked on division of whole numbers by unit fractions (fractions with 1 as the numerator). After doing a couple of models for problems, students were able to see that when multiplying by a unit fraction, you simply multiply the whole number and denominator. We will use this as a starting point tomorrow when we divide fractions by whole numbers.
Today's homework: page 769-770 Today we practiced multiplying fractions and mixed numbers today. Everyone did a great job with converting their mixed numbers into improper fractions and then multiplying! (See notes below)
