Today we worked with rounding fractions to the nearest benchmark fraction (0, 1/2, 1, 1-1/2, etc) to easily add or subtract for estimates. You can see our work in the notes to deciding which benchmark the fraction is closest to. As we worked on this we highlighted words or phrases in the number stories to help us decide if the problem was an addition or subtraction problem.

Today we reviewed and took notes on solubility. We compared saturated solutions to stuffed backpacks were no more gloves/books, etc could fit. We will be continuing our talk tomorrow as we make our super saturated solutions. Please make sure that your child has brought in a glass jar. We also need one more box of Borax soap for this activity.
Today we reviewed the crystals of our solutions from the past couple of weeks. Students made drawings in their science notebooks of what each crystal looks like so that we can use them later to help with our materials identification target.
Don't forget that students need a glass jar by Friday for Super Saturated Solutions activity We took time today to review our past work and what students had worked on with Mrs. Berg while I was at a conference on standards-based grading. We worked mostly with creating number stories, developing models to represent the number stories.
HOMEWORK: TEACHER-MADE WORKSHEET ON NUMBER SENTENCES, INCLUDING IXL SKILL D.11 TO REVIEW DIVISION Today students used their data from yesterday's experiment (the Newton's finished today) to determine what the Mystery Chemical was from a given Chemical Data Sheet. Students had to use what they knew about solubility to prove their answers. This assessment goes towards our "Materials Identification" target.
Next week, we will be looking at the crystal left behind from our citric acid and "mystery chemical" solutions to see if we can use that property to distinguish between chemicals. We will be doing a fun activity with super saturated solutions next week- Thursday or Friday. Students will be learning about how temperature affects solubility and then seeing in real life how that works. For this activity, each student needs to bring in a glass jar to use for their solution. They will bring them home during the last week before vacation. Additionally, I will need one box of Borax soap per homeroom- Arbour's homeroom is all set because one was brought in today. Today we reviewed how to model division story problems by identifying the number of items being broken up (how many wholes you need) and how many people/things will be sharing those parts (number of pieces to break them up into). We then made the connection between division and fractions. For example, if you break up 4 things into 6 parts, each part will be 4/6 of a whole. Students then practiced making number stories around given fractions and the context provided by classmates- some got very funny!
Today we started work on our fractions unit (3) looking at making models for story problems. Based on the pre-assessment, all students needed work on this. We worked through the 4 story problems in student math journals (page 71) to go through how to determine how many parts were needed and how to divide up those parts.
HOMEWORK TONIGHT: HOME LINK 3-1 Today students used their established procedures to figure out how much of a mystery chemical it takes to saturate 50ml of water. Students will use their data to determine what the mystery chemical is using a chemical data sheet. This assessment on being able to identify materials based on their properties (solubility) will be tomorrow. Today we spent time talking about answers where students are asked to explain their work or how they got an answer. In general, our students tend to do poorly on questions where they are asked to write about their work. I took one question from our recent test and typed it up with several answer examples from students on our team. In small groups, students reviewed the responses and talked about the things that we done well and areas that could be improved to better communicate student understanding. I forgot to take pictures of the notes, but students from both classes identified the following areas as places that most responses needed improvement:
-using examples (or actual numbers from the problem) in the response -giving specific details -including information about why you did what you did or where you got your information from -using specific vocabulary Students will be completing a worksheet that mirrors the work discussed today. It is short, so time should be dedicated to giving really good answers. HOMEWORK TONIGHT: COMPLETE STANDARD NOTATION WORKSHEET WITH FOCUS ON EXPLANATIONS Today we watched three videos on matter and its properties to go along with the investigations that we have done in the last few weeks. We took notes (seen below).
