Weeks 12/13

We have been so busy with the move to our new space, that I have not had time to post. I hope you can forgive me.

We have started our measurement work – naming units of measurement, knowing whether the unit should be used for indicating length, weight or volume, and converting units. We are continuing to review area and equivalent ratios. Th e students are absolutely loving our new space!

Student Goals

  • Generalize (orally and in writing) that it takes more of a smaller unit or fewer of a larger unit to measure the same quantity.
  • Given a measurement in one unit, estimate what would be the same amount expressed in a different unit, and explain (orally) the reasoning.

Week 6 – Ratio

Ratios and Ratio Language

  • Comprehend the word “ratio” (in written and spoken language) and the notation (in written language) to refer to an association between quantities.
  • Describe (orally and in writing) associations between quantities using the language “For every of these, there are of those” and “The ratio of these to those is a:b (or a to b).”
  • Draw and label discrete diagrams to represent situations involving ratios.

Student interpretations of a 1:2 ratio:

Area of Irregular Shapes

CCSS.MATH.CONTENT.6.G.A.1
Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes

Week 5 – Discovering a Formula

Students reviewed the important concepts from our recent investigations, and determined a formula for the area of ANY parallelogram using the base and the height.

Students drew diagrams to show that the area of a triangle is half the area of an associated parallelogram. 

Students determined a formula to find the area of ANY triangle.

 

 

 

 

Week 4 – Bases, Heights, Nets

Learning Goals

  • Comprehend the terms “base” and “height” to refer to one side of a parallelogram and the perpendicular distance between that side and the opposite side.
  • Generalize  a process for finding the area of a parallelogram, using the length of a base and the corresponding height.

Can you apply your process to any quadraleteral?

Folding and Unfolding Objects: Understanding Nets

Math with Janeen has started!

Math class meets M W F at 10:15

I am so excited to work with these amazing students! We began by watching a video from Stanford Mathematics professor Jo Boaler, focusing on 4 really important messages that we will be reinforcing throughout the year.

After we discussed the video, we talked a bit about the difference between a fixed mindset and a growth mindset, and students did a self-assessment as to their mindset.

FIXED MINDSET: Assumes intelligence and other qualities, abilities, and talents are fixed traits that cannot be significantly developed.

GROWTH MINDSET: Assumes intellligence and other qualities, abilities and talents can be developed with effort, learning and dedication over time.

On Wednesday, we started with Which One Doesn’t Belong? WODB activities help students to develop reasoning skills, make logical arguments, express their ideas in words, and engage with visual mathematicswhich ultimately leads to deeper and more meaningful understanding of challenging topics and concepts.
Next, we did our first MATH MINUTE. Math Minutes are sets of 10 problems that students do on their own, then discuss as a group. The discussion helps students to articulate and share their reasoning, politely give and accept criticism, be comfortable with mistakes, and build math fluency. The problems provide students with practice in every key area of sixth-grade math instruction.
  • computation
  • number sense
  • reading graphs
  • problem solving
  • patterns and sequences
  • date analysis and probability
  • spatial reasoning
  • fractions
  • algebra and functions
  • geometry
Together, students worked on the Four 4’s task. For students, this is a very safe and non threatening activity. It builds number sense and is a fun challenge. This task is also a really nice way of helping them become comfortable sharing their work in front of the class.

On Friday, students discovered that they could not seem to complete the Four 4’s task. I showed them factorial (!) which is very helpful for 11 and 13. We had some WWDB? discussions and completed Minute 2. Next up, tiling the plane.
