## Paper Roller Coasters

Students had the opportunity to build paper roller coasters as an enrichment math project. They had to design the coasters to include certain specifications and were provided a limited budget. There were several rebuilds along the way, but I am truly impressed with the wonderful coasters the students created!

Shout out to Martic Second Grade for testing our coasters!

## Math Homework for 3/19/2019

I have three math homework papers on my classroom floor tonight. This means that a few students may have accidentally dropped their homework. If this is your student, I have posted a picture of the homework to our Class Story. Have a great night.

## Good Luck Martic 4th Grade Math Bowl Team!

Our 4th Grade Martic Math Bowl team is ready for the competition! They have worked very hard and we all wish them good luck today!!

## STEM CLUB: Water Filters

In our after school STEM Club, students have been working to construct water filters. Their objective is to build the least expensive (from commonly available parts) water filter, that cleans the water the best, and the quickest.

Students purchase materials and evaluate their possible scores, given how much money they spent, using a cost analysis rubric. Next, they test their materials to see what works best and redesign their filters if needed.

The water is judged on color, clarity, smell, and particles.

Students have done an amazing job designing, creating, and testing their filters!

## Math Assembly

Our math assembly from this morning. Students worked in stations to complete math problems and learn about topics such as binary programming, the Fibonacci sequence, and more.

## Math Facts

As we come to the end of October, students have been working hard to master their math facts in multiplication.  The goal for our class is for every student to be able to complete their 1’s, 2’s, 3’s, and 4’s by November 1st (That is this Thursday)!  We have made great progress but need your help!

Ways to aid your students in their Math Fact Mastery:

• Flash Cards – Have students create and decorate their own Flash Cards.
• Play Multiplication War- Each player flips two cards and multiplies. Whoever has the highest product keeps the cards.
• Roll the Dice –
My students love Multiplication Roll ‘Em! Each student rolls two dice and multiplies the two numbers together.
• Awesome Arrays –
An array is an arrangement of similar objects, usually in rows and columns. Using unusual objects helps the concept stick.
• Play Bingo- Make Bingo cards out a piece of paper with multiplication problems (example 6 X 8) and call out products.
• Line Up Dominoes –  Line the Dominoes up parallel to one another.  Race to answer the math facts against a friend or quiz yourself.

## 3D Shapes and Bernoulli’s Principle

In math class we used windbags to create three dimensional shapes.  However, before we could use the windbags we had to decide on the best way to inflate them.  We estimated it would take between 200 and 300 large breaths of air to fill a big, therefore we needed an easier way.    After a quick demonstration of Bernoulli’s Principle we discovered a fun and quick way to fill our windbags!

## Art with 2D Shapes (Creating Our Own)

We have learned about 2D shapes such as triangles, squares, rectangles, rhombuses, hexagons, octagons, pentagons, and many more.  We combined our 2D shapes to make pictures and create puzzles.  Here are just some of our creations:

## I KNOW IT

I am pleased to inform you that your child will be using iknowIt.com, a new, interactive math practice site. Students will be able to use this website to review math skills that we’ve learned about in class. Your child may access the site from any tablet, laptop, or desktop computer.

When your child logs into the website, he or she may see assigned lessons from the teacher. If there are no assigned lessons, students can explore the site to find specific math topics we’ve been learning about.
When your child completes a lesson on this site, the score will be sent to the teacher.
