Show What You Know!

Yasmin blew us away yesterday, when she used an open number line to solve the following problem:

452 = n + 323

Her strategy was awesome and she was able to show and explain her work! Good mathematicians can always defend where they got their answer!

Show your work!Nancy, Francisco, and Alaina did a great job showing their work on the following word problems. I like how they used numbers and words to explain their thinking! Can you aspire to make your work like theirs? What strategies can you borrow from these learners?

The 3 A’s Game!

Today we played a new game to help us think deeper about our math strategies. We worked on our 3 A’s:

Agree!
Argue!
Aspire!

To play this game we looked at a math problem that had already been solved. We picked one thing that we agreed with. For example, “Oh, this student used the correct numbers.” or “I can see that they chose the right operation because this is a multiplication problem!”

Next, we had to find something to argue with like, “I would have drawn out based ten blocks instead of using the algorithm,” or “They chose the correct numbers but the wrong operation, they should have divided.”

Finally, we chose something that student did that we could aspire to! For example, “I like how they drew pictures to visualize their math,” or “I like how they wrote their answer out in words so that they could check if they really answered what the questions was asking.”

We are going to continue using the 3 A’s strategy to learn from our peers and aspire to their greatness!

Another Snow Day!

Hello Antwan, Nancy, Shannallie, Karmyn, Yasmin, and Ixell!

I had a feeling you’d be visiting the blog today when you took a break from playing in the snow (please remember to where hats and mittens!) Did anyone else visit today who I didn’t list? Let me know by leaving a comment!

Here are some word problems to keep your brain working on this very cold, winter day!

1. Antwan ran 444 yards in his first game playing football for Florida State. In his next game, Antwan, threw for 156 yards. How many yards total did Antwan move the football down the field?

2. Yasmin has 6 packs of crayons and each pack has 8 crayons. The crayons in each pack are red, yellow, blue, green, orange, purple, brown, and black. If Yasmin gives Karmyn one pack of crayons, how many total crayons will Yasmin have left?

3. Shannallie, Nancy, and Ixell ran 3 miles each day last week. If next week they plan to run 5 miles each day, how many miles will they each run after both weeks?

Leave your answers in the comments and I’ll come up with more questions just for you!

Here are some of my snowy day pictures from yesterday!

Solve a Word Problem by Visualizing!

We have been successfully tackling two step word problems with week using the CUBES strategy! Today, we want to think about visualizing the problem by drawing pictures like Francisco did yesterday with this problem:
Most apples contain 5 seed packets called carpels. Each carpel contains 2 apple seeds. How many seeds would be in 10 apples.
Francisco drew out one apple with five carpels in it. Then he put two seeds in each carpel. He skip counted by twos and determined there are 10 seeds in each apple. Next, he reread the problem and realized he needed to multiply 10 x 10 to get the number of apple seeds. His answer was: There are 100 apple seeds in 10 apples.
This lesson explains what Francisco did yesterday!

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
