Angle Tangle Game by Lily

The Angle Tangle math game is when you and your opponent draw a random angle without measuring and your opponent quickly measures your angle. Then you measure the angle to make sure your opponent's answer is right, if your opponent's answer is not correct tell your opponent the right answer and tell her/him how you got the correct answer. You & the opponent switch turns. The object of the game is to get one degree off or completely right, that counts as right.

How to Play Beat the Calculator by Cameron

For Beat the Calculator, you get a sheet and pick two cards. There are three players: the Caller, the Brain, and the Calculator. 

The caller calls out a problem using the cards. The player with the calculator has to beat the Brain and the Brain has to beat the Calculator. Then, if the Brain or the Calculator gets the answer correct, they win. And for the Calculator, you can't use your brain, you have to use the calculator. And the Brain can't use the calculator.

Play it, it's fun!!!

Multiplication Baseball by Connor

Multiplication Baseball is fun and competitive. The competition when you get to bat and you try to get on base. It is also when you're pitching, to try to never get easy an multiplication fact. And when you get up to bat, you always want to get a lucky fact.

It is fun when you are trying to get on base. When you are with your friends it makes it more fun. In conclusion, Multiplication Baseball is fun.

In the video above, Connor and Lucas demonstrate an inning of Multiplication Baseball. 

How to Do Traditional and Extended Multiplication by Caroline

Why traditional and extended multiplication are important

Traditional and extended multiplication are important because you need to do them at random times. So for example, when you're at a grocery store and maybe you need to multiply the prices. It would be weird just standing at the register and not knowing what traditional and extended multiplication are. So for example: 5 bananas in each bag and you're getting 30 bags, so: 30 * 5 = 150.

Another example is if you have a job, you also need to know it at random times. So for example, if you wanted to know how many workers there would be in 2 days and there were 15 workers each day, you would have to know 15 * 2 = 30.

Traditional and extended multiplication are important.

In the videos below, Caroline demonstrates how to use the traditional algorithm to multiply by one and two digit multipliers.

Room 101's Math Class by Braiden

Lately in math we have been learning how to multiply 2 digit multipliers and 1 digit multipliers. We have practiced doing them with the traditional algorithm.

We have done something called hot calls. What we do is Mrs. Mills or Mrs. Barnett write a rounded fact and everyone does it in their head. Then Mrs. Mills or Mrs. Barnett calls on anybody (you don't raise your hand). Then, the person answers it. Next, the class agrees or disagrees. Finally, we do the next problem. Hot calls are normally in the mini-lesson.

A mini-lesson is what we do every day in math after our math message. In the mini-lesson we learn about what we will practice. After that we do a sheet or math journal page to practice what we learned. And that is room 101's math!

 Doing the math message before the mini-lesson.

Baseball Multiplication by Connor

I think that math games are very fun. My favorite one is Baseball Multiplication. It is very fun.

One person puts their guy on home and the pitcher puts down cards. If the product of the cards is 1-21, it's an out. Other products are a single, double, triple, and home run. Win points and play.

Note from the teachers: in the video above, Connor and Dylan demonstrate how to play an inning of Baseball Multiplication. This game can be played at home in the Family Game Kit!

Math Olympiad by Cate

Today, the day after Thanksgiving break, some 4th and 5th graders showed up at room 206 for Math Olympiad! It's great for people who love and are very interested in math. So if you want to go, I bet you're going to be great!

Math Games Fun by Nick

The games in math are fun, like Polygon Pair-Up, Name that Number, and other fun stuff.

A lot of kids in our clas like the math games.

When Mrs. Mills or Mrs. Barnett say it's time to play Polygon Pair-Up, I like to play it.

(Note from the teachers: the video above is a video Nick made to demonstrate a round of Name that Number.)
