Fraction and Decimal Art

In Grade 4, we have been investigating the relationship between fractions and decimal numbers. 

As mathematicians and artists, we started off this inquiry by creating pixel art using Google Sheets by 'filling' squares out of a 10 by 10 table. 

Once we counted the number of squares of a certain colour to find out the fractional value, we converted the value into a decimal number!

(example: seven squares purple out of a hundred squares = 7/100 = 0.07)

After this task, we started working with more complex numbers and how division can be used to convert fractions into decimals.

See you next time!

Math Visual Proofs

As mathematicians, we are working on becoming good communicators. 

We know that mathematicians show proof of their thinking while making sure their work is precise. 

Right now, our focus is placed on creating visual proofs for multiplication and division problems. 

We began our learning process by working together to make sense of these visual proofs.

Take a look at the video to see how we worked with our classmates to figure out what was going on in the four sections!

Below, we have the learning intention and success criteria we created for this task. 

Check out the visual proofs we have created so far as we drafted and revised our posters!

 

 

 

Our next step is to apply the skills we developed during this assignment to create visual proofs for division problems as well. 

We are thinking about the following question:

How are multiplication and division connected?
