Division Representations Using Google Drawings

Here are our division representations using our favorite… GOOGLE DRAWINGS! So impressive!

Addition and Subtraction Representations

This week in the computer lab, we made Google Drawings representing several ways to solve addition and subtraction problems. These include equations, strip diagrams, and story problems. Mrs. Cross modeled how to do this on Google Drawings only twice and they were able to create these! They inserted text boxes, shapes, pictures, and lines. They learned how to change font and photo size. They’re well on their way to becoming Google Drawings experts! Click to enlarge the picture.

Bar Graphs Using Google Drawings

Today we created bar graphs using Google Drawings! The only directions I gave were to make a bar graph using scaled intervals. I am SO impressed with their creativity and critical thinking skills!

Class Pictograph

Today we made a class pictograph over how many multiplication tests we have mastered.

I’m so proud of the high level questions that the kids generated by themselves! Most of the questions require 2-3 steps!

Smart Lab games

Last week we made our own math and language arts games! We created our own questions, typed them into the SMART software, and then played each other’s games. What better way to practice skills than to play a game! Check out our video to see the types of questions and games we came up with!

Tuesday Morning Math Challenge

Today’s math challenge had a depth of knowledge level 3 (which ranges from 0 to 4)! With a depth of knowledge only 1 away from the hardest, their brains were definitely using critical thinking skills this morning!

 

Here’s the video of Austin and Jackson explaining their solutions that were 2 away and 329 on the nose! They even got closer to 329 than Mrs. Cross did! The closest Mrs. Cross could get by herself was 348!

Monday Math Challenge

This morning I gave my students this math challenge from Robert Kaplinksy. Here’s the problem:

We had 4 students who were able to solve it!! We found 2 different solutions, which is why we only have 2 videos.

Here’s how Jackson and Austin solved it:

Here’s Gavynn explaining how him and Sophie solved it!

I’m super impressed by their critical thinking so early on Monday morning!

STEM Olympics 2018 from San Antonio, TX

It’s no secret that we’ve been celebrating the 2018 winter Olympics here in our 3rd grade classroom! My students made bobsleds, snowboarders, hockey equipment, and curling stones. We tested each of them out and even awarded some medals for bobsled and snowboard races on the playground slides! Here are a ton of pictures and videos! We even coded our robot Dash to curl and hit the button on the curling house! Jackson made Dash a Lego Olympic torch too! It’s been fun learning about the Olympics and celebrating engineering week at the same time! #CrossCoders

 

Finding Area and Perimeter using Square Floor Tiles

I created a math activity where students used 12 inch by 1 inch strips that match the length of the edges of our 12 by 12 inch square tiles. Here are some of the challenges as well as multiple solutions for each task. That is one of my favorite things about math… we can solve problems in multiple ways and they can all be RIGHT!!!

  1. Create a polygon that has a perimeter of 8 units. What is the area?

Mia, Zander, M’Kale’s solution

2. Create a polygon that has a perimeter of 12 units. What is the area?

3. Create a polygon that has a perimeter that is twice as big as its area.

4. Create a polygon in the shape of a letter of the alphabet. What is the perimeter? What is the area?

5. Create 2 different polygons that have a perimeter of 16. Are their areas equal or not?

These 2 polygons ended up having the SAME area and perimeter!!!

Here is another set of pictures from a different group. These following two polygons had the same perimeter, but different areas!

 

Arrays

Today we challenged ourselves to find all of the different arrays for the products of 16, 18, 24, and 36. Here are our Seesaw posts from the activity. The product of 24 had the most arrays at 8. The product of 16 had the fewest arrays at 5.
