March 2019 - Down River Resources | Your Elementary Math Guide
Comparing numbers can be difficult. Young mathematicians, especially in kindergarten, just become proficient in learning the quantity of numbers before diving into comparing those numbers. For decades, teachers have relied on the 'ole alligator analogy for teaching students to compare numbers and draw comparison symbols. You will find numerous blog posts and printables with this cute alligator, even suggesting to use him with decimals and percentages. Have you or your students become dependent on drawing teeth on comparison symbols? Students think, "Is the bigger value eating the smaller one?" or "Is it the value it already chopped on?" This becomes confusing, especially for younger students. While this can be a cute anchor chart, students are not internalizing the meaning of the comparison symbols. This misnomer is confusing children and frustrating their future teachers. I know what you are thinking, if the alligator analogy isn't the best for students to learn, what can I teach my students so they can retain the correct meaning for these symbols? Read more to find a strategy for teaching comparing numbers and correctly explaining comparison symbols.

There's A Better Way To Compare Numbers

Thinking about how a child learns vocabulary, it's easy to roll back time and reflect on how a young child learns their name. How does a child learn their name? Parents have identified the child by their name. The parents and others around the child use their name in context. With repeated exposure to their name, the young child memorizes it. Soon they are able to repeat their name and identify themselves as such.

Children are innately logical and literal. If we say "alligator," children think of the lizard-like swamp animal, not a mathematical symbol. 

If adults call a comparison symbol an "alligator," we are mislabeling a content-specific word for students.

I truly believe this is what happened in my early education. I learned tricks in school, not actual mathematics. Eventually, there comes a point when tricks no longer suffice for students and can lead to failure in advanced mathematics, which is the WHY behind everything I do with Down River Resources.

There is a big movement, especially in upper elementary, middle, and high schools to break students away from these misrepresentations.

Trust me, I know it is not ANYONE'S intention to teach incorrectly, often times, we are victims of our own education. Educators teach the way they were taught unless they have since learned differently.

How Do I Teach Comparisons?

Use a word problem to introduce two sets of numbers. If you are comparing numbers 9 and 7, it may sound like this:

Kaila and Marco were born on the same day. Kaila has 9 birthday candles on her cake. Marco has 7 candles on her birthday cake. Use a comparsion symbol (>, <, or =) to compare 9 and 7.

Ideally, with exposure to symbols, such as in the word problem above, students memorize the meaning. Just as students hear comparative language, such as "equal to," "greater than," and "less than," they need to see the symbols that represent these phrases too.

After modeling this language and its corresponding symbols, the students should practice saying and writing them too!

If you are still stuck on the alligator so the students have a scaffold for learning the comparison symbol, I have a strategy to help. 

Sometimes before students can internalize the meaning of the symbol, it helps to actually analyze the shape of the comparison symbol.

Why You Need to Ditch the Alligator When Comparing Numbers and Strategy Support
Think about an equal symbol. 

The line segments are parallel; the bars are the same distance apart on both sides. (See the "equal to" image.)

Now, let's take a closer look at the symbols that represent inequalities. 

The segments, or bars, are tilted when using the inequalities. There is a smaller side and a larger sides.

The GREATER number is next to the wider end, while the LESSER number is next to the narrower end. 

Please note the language used in that statement above. Use GREATER instead of 'bigger,' and LESS rather than 'smaller.'

Why You Need to Ditch the Alligator When Comparing Numbers and Strategy Support As students move into advanced mathematics, students will need to apply this skill to integers. Calling -6 'bigger' than -16 creates confusion for students.

As you can see below, EVERY grade level focuses on comparisons to some degree. 

Let's commit to focus on teaching mathematics, not just the tricks!

Why You Need to Ditch the Alligator When Comparing Numbers Strategy

One of the best things about teaching history during Women's History Month is the accessibility of quality children's literature or picture books! Students are much more likely to learn about the important events, people, and places which make our world unique through an accessible text. Throughout our history women have made valuable contributions. No matter what their role, women's experiences remain an important and sometimes overlooked aspect of our history. I've included some historical texts and a few inspirations book for young girls. These picture books value the diverse experience of women and provide inspiration for the young girl sitting in our classroom or being raised within our home.

The social component of working on a game in a group leads to LOADS of benefits on brain function including:

- Activate neurotransmission
- Increase brain plasticity
- Rewires
- Mitigates brain inflammation
- Mitigates deleterious effects of oxidative stress

These are just the benefits of the social components of gamifying educational content.

Adding learning games in your classroom will boost intrinsic and extrinsic motivation, engagement, and learning outcomes for learner!

With so many benefits, what are you waiting for friend?

My favorite way of gamifying the classroom is by simply adding a popular game to test prep sessions.  

Want to do it too?

Here's How To Test Prep with Ease:

Collect a game or gameboard. Goodwill and Savers are the best cost-savings options. I often find games on clearance too!

Use word problems or sample test questions as the educational basis of the game. You can use questions from worksheets, released test questions, or specific game cards to practice heavily-tested standards. (In Texas, we call these the readiness standards.)

Rigorous game cards

The class can be divided into two teams. The team can work together to solve the problem.

If the team gets the problem correct, the team has a turn to play the game. Students within each team can take turns being the “player” for their team by following the game’s instructions.

If the team does not get the problem correct, they forfeit their turn. {You can also create a “Steal” option. The other team can generate a solution for an extra turn. You can give teams a couple extra chances to use through the game, three strikes, etc.}

Connect Four Shots

Are you ready to try this strategy, but need test-like questions to minimize your prep time?

I'll keep you afloat with my math test prep bundles that are just waiting for you to print. These will surely add some challenge into your math test prep sessions. They can be used during testing season or throughout the year for a spiral review. The bundles come with printable game boards OR you can add your own physical game too. 

I hope this post inspires you to gamify your test prep sessions, if you need Connect Four Shots,
you can find it here.

The rigorous test prep bundles can be found in my TpT shop:
