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.

Math Homework for 3/19

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 Facts

Hello 4th Grade Families!

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:
