A Great Math Week!

We are about to have a fabulous week of math centers! I have been hard at work preparing fun ways for our class to review for the End of Grade test! This week you’ll have opportunities to practice adding, subtracting, multiplying, dividing, working with time and money, graphing, area and perimeter, geometry, and more! All of our centers will include games and partners to help you stay engaged in your learning! So get your math journal and a pencil and get ready to have some fun! 

Awesome Centers from the Busy Class on TpT

Pablo really likes the telling time game!pablo plays math ceners by The Busy ClassWe send a big thank you to The Busy Class and K-5 Math Teaching Resources for creating such awesome centers for us!

Also, I found a rhombus on Pablo’s head! Crazy!

Pablo has a rhombus!

Math in Action!

We took our whole class math block to a whole new level this week! We played “Agree, Argue, Aspire”, worked in teams and independently, took our fraction knowledge deeper, and capped it all off with multiplication Jeopardy! Our class was focused and engaged all week long, and you have made me so proud!

We studied Karmyn’s work on her practice EOG test. Check out how she tried three different strategies before getting an answer with which she was confident! Karmyn’s work showed us that she can truly persevere when things get tough. Her example gave us a lot to aspire to!

Don’t be afraid to try more than one strategy!

Never be afraid to start all over!

Here we are studying Karmyn’s work and deciding what we agreed with, what we wanted to argue with, and what we could aspire to do in our own work!

Number line or Fraction Model

number line or fraction modelWe have been looking at different methods of representing fractions so that we can picture them in our minds. Two strategies we have tried are, representing fractions on a number line and drawing out fraction models . Both strategies help us visualize the fractions we’re working with and make it very easy to see if two fractions are equivalent.image image image image image

So, which method helps you visualize the fraction better, fractions on a number line or fraction models?

More fraction games!

Alaina helped me realize today that I had never put the amazing Balloon Pop fraction ordering game on our blog! Thanks Alaina!

Remember, the shaded areas of each balloon represent the fractions. Work from the smallest to biggest fractions popping the balloons! Click the game below.

Here’s a new game to check out! This game has you estimate where fractions fall on a number line based on the fraction’s size. Remember to ask yourself what we practiced in class, “Is this more or less than a half?”

No not Fractions!

When Mrs. Felter was just a little Jessie, she hated fractions, but her mom never let her say “hate”, so she just disliked fractions thoroughly! She hated fractions because she just didn’t get them. Now that she is all grown up she realizes that fractions are actually really simple! The most important part of understanding fractions is figuring out how a whole can be split into many equal parts! Check out these fraction games to help you figure out the mystery of fractions without having to “dislike them thoroughly!”

Decomposing a Kilogram

On Monday, we sat down and took a kilogram apart. A kilogram is a unit that is used to measure weight. Often grocery store items are measured in kilograms. We learned that:

1 kg = 1 kilogram!

By decomposing a kilogram we discovered that:

1 kilogram = 1,000 grams or

1 kg = 1 g!

We also determined that 100 grams could go into a kilogram 10 times and 10 grams could go into 100 grams 10 times! Check out these mathematicians at work!

Division Stories

Division problems can be tricky when you first try to attack them! Coming up with a story to go with your problem can help you understand what the problem is asking you to do. For example the problem  10/5= x can look confusing. But when you write a story for it, it is easy! Look at this division problem below from Mrs. Harris’ class.

Here is another problem to consider:

18/3 = x

To solve this problem I can come up with a story to help me think about splitting 18 three different ways. Here is my story:

I have three boxes to carry 18 cupcakes in to school. If I want each box to contain an equal number of cupcakes, how many cupcakes will end up in each box?

Now I can draw out pictures of the boxes and split the cupcakes into each one. After I split up the cupcakes equally, I see that I have six cupcakes in each box. 18/3 = 6

It’s your turn! Write a division problem for this equation:

24/4 = x

For our Math Blog Center this week, write division problems for the following equations. Draw pictures, and solve the problems. Remember to write your problems out on the center paper and leave a comment as well!

12/6 = x

24/3 = x

30/5 = x
