Fun Algebra Easter Egg Hunt Activity

Just a quick post today to share a fun, quick Easter activity I’ve done in the past with Algebra/Pre-Algebra classes in case you want to try it…

Fill up an odd number of Easter eggs with pennies (put the same number of pennies in each egg).  Hide the eggs in the classroom before class begins.

When the students come in, ask for 2 volunteers.  Have those 2 students search for Easter eggs.  Since you have hidden an odd number of eggs the two students obviously will have found a different number.  Tell them that you want to be fair so you are going to even out the amount of money each student has by giving them some loose coins.

In the picture, you can see student A only found 1 egg and student B found 4.  So, I gave student A $0.25 and student B $0.04 to even out the total amount of money each student has.

Ask the class to figure out how much money is in each egg.  (You can give the money to the first student to get it correct as a prize if you want.)  Discuss how they figured it out and prove they are right by opening the eggs (in this case there is $0.07 in each egg).

There you have it – a fun way to have students solve equations with variables on both sides (without them even realizing that’s what they are doing!)

Enjoy!

Breaking Down 2 Step Equations

Today I’m writing about a simple idea that makes 2-step equations easy for kids – a box “trick”.

2 step equations box trick

Students obviously have already learned how to solve one-step equations before being introduced to two-step equations, so I introduce 2-step equations by giving students a simple one-step equation.  The only difference is that I use an index card instead of a variable in my equation.

box trick pic1

Put an equation like the one pictured above on the board and tell students to solve it for the index card, which they should be able to do easily since it is a simple one-step subtraction equation.

Once they solve the equation for the index card, lift up the original card to reveal what is underneath it (in this case 8x).  It also works if you write 8x on the backs of the index cards and just flip them over.

box trick pic2

So, since the index card = 8x they now need to solve the equation 8x = 56, which is another simple one-step equation that they should already know how to solve.

box trick pic3

Do another example or two with the class and then discuss how to decide which part of the equation goes under the index card (whichever part comes first using the order of operations).  Have students replicate the process in their notebooks by giving them a 2-step equation.  They need to draw a box around the part that would be under the index card.  First solve the equation for the box and then solve the new equation for the variable.

I have found that this method really helps students make sense of solving 2-step equations by turning them into two 1-step equations.  How do you introduce 2-step equations in your class?  Do you do something similar?  Please share in the comments!

Turn Multi-Step Problems into Team Activities

Let me start by saying that relays are not an original idea..maybe you have been doing them for years…but they are new to me, (and i love them) so I figured I’d share in case anyone else has never tried relays with their class.

team relays

How they work:
Take a problem that requires multiple steps to solve, and break it up into however many steps you need to solve the problem.   Then break your class up into groups that are the same size as the number of steps in a problem.

For example: Multi-Step Equations

I came up with the following 5 steps:

  • distribute to clear any parentheses in the problem
  • combine like terms within each side of the equation
  • add/subtract to isolate variable terms from constant terms
  • multiply/divide to solve for the variable
  • check by substituting answer in for variable

Since it is a 5 step process, I need to break the class up into groups of 5.  (If your class size doesn’t divide evenly by 5, you can make some groups of 4).

Give the class a problem, assign each student in a group a step of the process.  Student 1 completes the first step and passes it to student 2.  Student 2 checks student 1’s work and then does step 2, etc. until each student has completed a step and the problem has been solved (and checked.). For a group of 4, student 1 will also complete step 5.

multi-step equations team relay

Repeat this process 5 times with 5 different problems, each time shifting which student starts the problem, so that by the end every student has had a turn completing each step.

I love this activity because

  • The students work cooperatively, but individually
  • The students are checking each others’ work
  • Relays really emphasize each step in a process

Make it a race if your class is competitive.  If you want to see who completed each part you can have them write in different colors.  Either have them sit in a circle if you want them to be able to help each other complete their steps or have them sit in a row if you want it to be a silent activity.

Do you use relays in your class?  If you have any tips, suggestions, or other ideas for them please share in the comments below!

If you don’t want to make your own relay and are looking for a pre-made one, I have one on writing and graphing linear equations (using point-slope and slope-intercept form) available for sale in my TpT store, which you can get to by clicking the image below.  I am planning to make several others on different topics in the near future, as well.

A Creative Approach to Grouping in the Middle School Math Classroom

I am a HUGE fan of group work!  I love having students work together in my math classes for practice work, problem solving, review games, etc.  Occasionally I allow my students to pick their own groups, but more often than not I assign them because:

  • No students are ever left out or the last one picked when I assign them
  • I can make sure the groups are either mixed ability levels or homogenous (whatever I need for a particular class period)

I pick new groups every time we do group work because I think it’s important for the students to be able to work successfully with different people and I don’t want students “stuck” with the same people every time.  I have done different things in the past to pick random groups such as having the students count off or handing them playing cards as they walk in the room.  I also have deliberately placed students in groups.  But I was looking for a way to mix things up…

…so I have come up with the following solution:  As the students come into the classroom I will hand them a card with a math problem they need to solve (relating to what they are learning).  This problem will be in place of the typical do now problems I give them on Socrative.  Once they solve the problem, they will need to find the table labeled with the answer to their card, and sit there.  (3 other students’ cards will have that same answer), so those 4 students will be a group for the day.   (I will be walking around to assist any students who struggle with their problem).

I am pretty excited to try this and can think of a bunch of different ways to change this up.  I could have the groups be completely random by just giving each student a random card, or I can make the “random” groups fit my needs based on ability level (without the students even realizing it) by grouping the cards based on difficulty level and giving each student a card from the group that is appropriate for them.  [If I want mixed ability level groups, the 4 cards with matching answers will be 4 different difficulty levels;  If I want homogenous groups, the 4 cards with matching answers will be the same difficulty level.]

Obviously this will require a bit of prep time in advance (since I have to come up with the questions), but I plan to laminate the cards and use them every year.  I can also re-use them as a card-sorting center activity, as task cards, game cards, etc., so I think that it is worth the initial time investment.  (There are soo many different ways that I can use and re-use the cards!!)

I made my first set of these cards on one-step equations and have them set up to create mixed-ability level groups.  I color coded the cards by difficulty level – yellow include only whole numbers, blue include integers, green include fractions, and red include decimals.  As the students walk in the class, I will give the students who struggle with one-step equations yellow cards, and the students who need more of a challenge green or red.  The groups will end up with one of each color card, giving me random, but “equal” mixed-ability level groups.
