Representing Numbers

Over the past month, we have been exploring representing numbers in various forms. As a class, we created a list of all the ways we could show a number. 

• Numerals (231)
• Base Ten blocks
• Tally marks
• Place value columns
• Expanded form
• Words (two hundred thirty-one)
• Equivalency scale diagrams
• Ten frames
• Picture
• Number line
• Fingers
• Hundreds

In Grade 4, students need to learn how to read numbers up to 10 000 and represent them using pictures, base ten blocks, words, expanded form, and know their value using the place value column.

Here are some ways we have been learning and practicing: 

• Place Value Riddles: I am a three digit number. I am even. The digit in my tens place is greater than 4. The digit in the hundreds place is odd. Who am I?
• Guess My Number: I have a number on my back. I can only ask Yes-No questions to figure it out
• Domino Games: Clockominoes, Bury the Bones, Trading Places
• Card Games: Place Value War
• Dice Games: Don't Break the Bank

If you are looking for ways to practice at home, playing these games together would be super helpful!

We played games where we built numbers with Base Ten blocks. We also worked together to build numbers using the base ten blocks in a guided lesson like this: 

This week, we are working on showing equivalency through scale diagrams. We can make the equations as complicated as we want to show our understanding of number. 

We will also explore expanded form. 

Students will have an assessment on Thursday, November 23. It will include these concepts listed above, as well as one bar graph question. You can take a peek back at our Graphing work here, if you need to.

To prepare for the quiz, students are encouraged to play the games listed above and teach you about this work.
