Laying the Foundation in Math


Our first week of 4th Grade Mathematics has been focused around gaining a deeper understanding of our Base 10 Number System. We began by exploring place value through looking at numbers in their standard, word, and expanded forms.

For example, 143 = one hundred forty-three = 100 + 40 + 3


We then began modeling numbers in our number system using open number lines and "play" money. These representations helped us make sense of rounding numbers to landmark numbers (friendly numbers such as multiples of 10 and 100).

Our next focus will be to use "rounding" to help us estimate sums (answers to addition problems) and differences (subtraction problems). We will begin that discussion on Monday.

This foundation we are laying through our study of place value, rounding and estimation will be necessary in understanding the higher level mathematics we will be studying the rest of our 4th grade year together.

The following link provides reinforcement and practice in the skills and concepts we have been working on in class. Students are encouraged to reference this site as one method for making sure they are prepared for our first math assessment of this school year, which will be this upcoming Wednesday, August 29th.

  4. I had fun doing math on the website. My mom and I did notice something weird with the "test yourself" sections. I clicked the correct answers on some questions, but the end of the test showed that I clicked the wrong answer. I paid close attention to it the next time, and same thing happened again. But over all it was helpful to practice the math. -Sydni
