Shhhhhh....! It's a Secret (Name Code)

Hi All,

We're probably all still learning each others' names at school at this point in the year, so here's one more "mathy" name activity.

Kids love secret codes and patterns. I think we all do actually. This is a simple code, but it lends itself well to differentiating a lot of mathematical operations.

Match every letter with its ordinal position in the alphabet––for example, A = 1, B = 2, C = 3, Z = 26. To get children started have them create a decoder chart where they list all the associated letters and numbers, A to Z, 1 to 26.

Next have students write their names out and pair with the associated number. So, J-A-N-E would be 10-1-14-5. Now, they should get a blank index card (the clue card!) and write out incomplete equations that will yield the numbers they need to "spell" their names.

Jane might use these:
5 + 5 =
100 - 99 =
7 + 7 =
9 - 4 =

This is where you can really differentiate. Students could use multiplication, division, subtraction, addition, even square roots or exponents to express the letters in their names, depending on ability.

Once the clues cards are complete, collect them and pass them out randomly around the room. Each student should use their mathematical knowledge and their decoder chart to figure out whose card they have by solving the secret coded name/message. As students complete the task have them return the card to the person named there.

Simple, but fun. Plus, it's a great beginning of the year assessment to see what kind of numbers and operations your kiddos come in knowing and are comfortable using as they create their clues.

Good luck this year, everybody. May the math be with you,
Bob

What Does Not Belong?

Hi All, "What Does Not Belong" is such a great little concept and can be applied to so many different areas of math as well as other content areas. Great little game when you are waiting, like for buses to be called or for the day to begin. Also a great game for long car or bus rides where if there are no written numbers or pictures you really have to do the mental math. Present a group of numbers. Start with maybe six. Say, 10 56 17 122 4 98 Ask the players to identify which number does not belong and have them explain why. We want players to look at the characteristics of the numbers and compare them to try to find the selection criteria or "rule" so they can determine which does not belong. For example, we have a mix of 1, 2, and 3 digit numbers, so it's not the "rule" is not the number of digits. We have five even numbers and only one odd number. That's it! 17 does not belong,...

EGG BOX SHAKE! IT'S WHATEVER YOU WANT IT TO BE.

Hi All, Shake it up! Egg Box Shake is noisy and fun! That's a big plus right there for most kids. Students like to create and keep their own math tools, and this is a great opportunity to do that as well. And, teachers can adapt the game to fit any level or mathematical operation. Win. Win. Win. Egg Box Shake originated as a coin identification and addition game for grades 1 – 3. I had students bring in an egg carton from home and then provided them with play money or coin stamps, ink pads, and card stock. They stamped out pictures of the coins onto card stock, front and back images, and then cut out the pictures. Students glued these pictures into the bottom of the twelve sections of the egg carton. Each player would get two beads, beans, chips, marbles, or any other small manipulative. They put these into the box and closed it. They then shook the box. When they stopped they opened it and saw where the beads had landed. Players added those two coins o...

What's in a Name? A lot of Math!

Hi All, Welcome back! With school starting one way or another in various parts of the country, I figured it was time again to bring back the math blog. No matter what's going on or how it's going on, I'm hoping this content will still be useful to you. So, let's talk about names! When classes start, one of the first things both teachers and students must learn about each other are their names. A child's name is a very powerful and important thing. It's also a great springboard to learning. Kids are always interested in their own names. "Names Add Up" is an easy activity for K-2 (though older kids like it as well) that combines counting, addition, and money, as well as vowel and consonant identification. You'll need a pile of pennies and nickels. Explain to children that for this activity vowels will be worth a nickel and consonants will be worth a penny. Have children take the coins that correspond to the letters in their first names and...
