We've begun a new module this last week. We've been discussing fractions and are beginning to find equivalent fractions. We are discussing what a unit fraction is and how to use them in addition and subtraction of fractions.

This weeks we will be learning the multiplication algorithm. First we will build a greater understanding of how multiplication works through place value and area model work. Then we will introduce the standard way to multiply, or in other words the way that you and I learned when we were in school.
Math this year has been great so far. Working our brains towards a greater understanding of numbers is hard work but so rewarding. Thank you for you support. This week we will continue to multiply numbers by 10's 100's and 1000's. We will be looking for patterns that will help us increase our understanding of how ad why multiplication works. To help your child to build some fluency in Multiplication and have some fun you could check out multiplication.com.
We are moving on to a new topic in math this week. The four lessons we will cover include
It will be a lot to cover but we are confident that student will find patterns in these skill quickly and be successful as we move through the next week. Here is a small video about what we are doing in class on Monday. This is a great channel on which you can find help with many of our lessons from class. We've spent this last week we exploring meters, grams, and liters. This week we will be finishing up this unit and taking a math test. Below is an example of what will be on the test.
Convert: 3 km= ______m 13 kg= __________g 7 L=______________ml 5 km 345 m=_________m 2 kg 47 g=___________g 96 L 345 ml=_____________ml Solve: 26 kg 23 g - 16 kg 15 g = grams 90 L 2 ml + 3,333 ml = L ml Joe is training for a marathon, use tape diagrams, numbers and words to explain each answer below Each day Joe runs on the treadmill for 4 km and runs outside for 5,000 m. In all how many meters does Joe run each day? Since Joe started training, he has been drinking more water. On Saturday he drank 3 liters 433 ml of water. On Sunday he drank some more. If Joe drank a total of 5 liters 673 ml of water on Saturday and Sunday how much did he drink on Sunday? We will be finishing up our unit on place value, rounding, addition and subtraction this week.
Students have been working really hard these last few weeks, setting up a strong understanding of place value. We will be taking a math test this coming Wednesday. We are excited to see how our students do. P.S. Here is a sampling of what will be on the test Compare the values of each 8 in the number 838,345. Use a picture, numbers, or words to explain. Compare using >, <, or =. 534 thousands + 4 ten thousands 641,000 4 hundred thousands – 1 ten thousands 30,000 Sacramento, Ca has a population of 742,321 people. Baltimore, VA, has 45,987 more people than Sacramento. Charleston, SD, has 496,804 less people than Baltimore. What is the total population of all three cities? Round to the nearest hundred thousand to check the reasonableness of your answer for the population of Charleston, SD Record each city’s population in numbers, in words, and in expanded form. Compare the population of Sacramento and Charleston using >, <, or =. The last two weeks have been a blast in math. We've explored numbers to a million. Found connections between thousands and hundreds, We've even had a chance to break out our new math manipulative and have some fun with those. It has been a great start to the year.
As we move forward this next few weeks we will be will be rounding, reviewing addition and subtraction. This year in math we will be doing some fun and challenging things.
Fourth grade has three major concepts in math Number and operations
Geometry
Fractions
We will be starting out the year with a review of place value and addition and subtraction. I hope you will visit this blog often to keep up to date on what we are learning and some great tools to help students and parents. We have covered so many topics in the last few weeks it's hard to keep them all straight. We've worked with Decimals, reviewed fractions. We have played with shapes and angles. Now we are spending a few day working with standard measurement.
If you've notice that math homework has been more scarce it's very true. If you ever would like your child to have a little extra practice they can log on to MobyMax or Zearn.org. The last two weeks we have been working with angles, shapes, and protractors and having a lot of fun. I had to chuckle as at my class as I was introducing this unit on Geometry so many of them made a whining noise and complained that Geometry was hard. But now they can't get enough of it. We are having a blast as we are moving through these lessons.
