Fifth graders work together to plan and develop presentations with a partner. Nice work!!
Nico and Hana figuring out how a stem and leaf plot works.
Max and Renee (and Lily) deciding what to work on first to prepare their presentation on line graphs.
Grace Karina and Ian add details to their bar graph online.
Hannah and Surina decide what data they want their circle graph to show.
No, no, not exercise….students delved into an early geometry lesson recently where they had to challenge their spatial reasoning. The project started with attempts at drawing 3-d cubes on 2-d isometric paper. Students then created orthographic drawings which show the object from the front, side, and top views. Finally, they created a foundation drawing which illustrates how many levels of blocks there are in the structure as seen from the top view. The exploration culminated with students creating their very own architectural designs through isometric drawings, and then making the orthographic top view and a foundation drawing of their buildings. Coming soon to a city near you….!
7th graders worked to come up with a creative explanation about why the inequality sign gets flipped when both sides of an inequality are multiplied or divided by a negative.
SHAZAM!!
(Special thanks to the 6th grade class for helping out!)
Welcome back to a great new year at TCPS!! I’m so excited for my new homeroom full of 6th graders and math classes galore!!!
Here are some tips to help you be prepared for your first days and weeks of school:
Can’t wait to see you all September 6th!!!

Fifth graders became interested in a VERY long number while making up equations. We had to research online what each period of numbers was called. We then invited first graders to come read it with us since they have been working on reading large numbers this year. This was the first number either class has read in the Quindecillions!
Seventh grade students plan graduation each year for the eighth graders. This year, they considered what would happen if we had to rent the chairs from a party company. Students researched online and made phone calls to determine pricing, and then wrote equations and created graphs to determine which company had the best prices based on renting anywhere from 0 to 500 chairs. Students prepared a report to submit their recommendations based on their findings. Click to see each student’s report.
We’ve been spending the past couple weeks understanding fractions and fraction operations. Students in fifth grade have been making some excellent hypotheses and asking wonderful questions about fractions. Here are some of the things they’re saying…
-2/3 x 3/5 = 6/15. I found this answer by finding 3/5 of 1 whole. The answer is 3/5. Then 3/5 became the whole. In other words, I am not finding 2/3 of a whole and 3/5 of a whole but finding 2/3 of 3/5. So I drew a picture to help me solve. I split a rectangle into fifths and shaded in 3 of them. I then covered that with 2/3 as 3/5 is my new whole. Then I shaded in 2 of the 3. This was 2/3 of 3/5. The answer was 6/15.
-2/3 x 3/5 was a very difficult problem but we figured it out. We got 2/5. It was 6/15 simplified into 2/5. It’s like you’re adding 2/3 3/5 of a time so it (the answer) would be smaller. 2/5 is smaller than 2/3 and 3/5.
-2/3 x 3/5 is a problem multiplying a fraction by a fraction. You will get a fraction of the original fraction. The product gets smaller.
-If you have a sheet of paper and you divide it into 5 sections you get 5ths. If you shade 3 sections in you get 3/5. You need 2/3 of that 3/5 so you take the 3/5 and split that into 3rds. Next you have to shade 2 of the 3rds you made. Now you have 6 boxes shaded. They are 15ths. Now you have 6/15 = 2/5 so 2/5 = 2/3 of 3/5.
-I noticed that the three in 2/3 times the 5 in 3/5 is 15 and the 2 in 2/3 times the 3 in 3/5 is 6. In total 6/15. Will this always occur when multiplying fractions?
-Will the way we did 2/3 x 3/5 work for every question like it?
Middle school students each shared two interesting facts about pi today to celebrate 3/14. A couple students referenced an old Star Trek episode where Spock used pi to outsmart an evil super computer. Math is everywhere!!
