Today was an early release day. I had the students practice for their SWYK on Monday. Check out the tutorial section on my website if you need any extra practice or help!
Today we did a quick review over how to divide fractions. We discussed both the divide across and the more traditional multiply by the reciprocal methods. Then we practiced multiplying and dividing rational numbers on IXL.
Today we reviewed multiplying fractions and mixed numbers. We looked at what it means to multiply fractions conceptually first, and then moved on to the algorithm. This is covered heavily in 6th grade, so we just did a quick overview. After discussing fractions, we continued multiplying fractions, but utilizing our rules for positive and negative numbers.
Today we explored how to multiply and divide integers. We utilized many models to help conceptualize this often non understood concept. We used the chip method, the number line method and looked at some patterns. Here is the record sheet students filled out as they were exploring multiplying and dividing integers:
Today, we started thinking about multiplication and division of rational numbers by looking at them in word problems. Students were asked to work together to model the problem and solve it using numbers, pictures or diagrams
Here is the worksheet we used. I'm back!They also got to play another rousing game of grudgeball to review for their SWYK over adding and subtracting rational numbers (which they took today.) Starting next week, we will be discussing multiplying and dividing rational numbers. I apologize for not updating the blog the last couple weeks. I had to take a few days off for a professional development day and to travel to Kansas for my sister's wedding. :)
While I was gone, students continued practicing adding and subtracting rational numbers. They solved problems using Tenmarks and completed the following puzzle: We've been incredibly busy the last few days in 7th grade math! Over the past couple days, we've finished our unit on adding and subtracting integers and decimals and practiced in multiple ways in class. We finished off with a rousing game of Grudge Ball on Friday (a definite favorite). Today the students will take their first Show What You Know over adding and subtracting integers and decimals. Then we'll begin adding and subtracting fractions.
We started off yesterday and today with a 24 problem. The numbers they had to use to get to 24 were: Level 1: 22, 9, 20, 13 Level 2: 8, 7, 24, 8 Level 3: 16, 9, 18, 8 We have been doing a lot of exploring with integers and looking at them in real life situations. Today, we tried to generalize rues for adding and subtracting integers. The students then put these rules in their notes. We are creating rules such as these to help extend the ideas of how to add positive and negative numbers to all rational numbers...including fractions and decimals.
Today we did a card sorting activity in which the students were given sets of cards that included cities, their temperatures, and arrow cards that indicated the change in temperature between the cities. In each case, there is a missing temperature or a missing change in temperature. Based on the 2 given pieces of information, their goal is to determine the missing numbers and show how they came to that answer. Most groups did not finish the activity, so we will continue it tomorrow. Not all groups finished organizing their flow charts, but here are a few that completed in class. Tomorrow, the students will have the opportunity to join groups to share their reasoning and thinking on how they completed the activity. |
