There are a lot of components to a math lesson. You look for activities with engagement and complexity to assess understanding. Sounds simple enough but there are several layers to each of those factors making it hard to find the perfect balance. So when I work with teachers on implementing number sense during their math class they start to panic.

*βHow can I add another thing to my math block?β*

*βI donβt have enough time!β*

*βI donβt know what type of questions to ask!β*

I get it. Youβre holding all these reminders in your mental filing cabinet when youβre teaching a lesson. You want to target specific standards and explain key concepts. You want to ask higher order thinking questions. You want your students to really grapple with concepts rather than memorize procedural steps.

**But guess what?**

Building number sense will ensure you target all those wants. Number sense is not another component to your math block. Instead it is part of everything you say and do in the classroom. Simply put…itβs good teaching.

### Questioning

A good math teacher is always looking for ways to sprinkle number sense into lessons, but it can be hard to find and/or write number sense connected questions.

Look for questions that are open ended, require critical thinking, and reinforce the concept that numbers can be manipulated. Be intentional in the types of questions you ask.

**Example: When rounded to the nearest hundred, I become 400. What numbers could I be?**

This question takes a standard (rounding) that is often taught procedurally in classrooms and requires students to conceptualize the concept of rounding based on the value of specific digits. Students must work backwards starting with a number that has been rounded to the nearest hundred. Students will first share the most obvious answers such as 399. It takes some time for the class to conclude that any number from 351 to 449 rounds to 400 if asked to round to the nearest hundred. This question is far more complex than, βRound 377 to the nearest hundred,β thus reinforcing number sense.

### Strategies

Some children have been given opportunities to build number sense at a very young age. Those students will appear to naturally understand how to manipulative numbers and place value for easier computation, while others will struggle. Educate your students on the different number sense strategies. Model these strategies time and time again. Constant repetition will help your struggling students develop number sense. Provide your class with daily prompts to drive the concept home. We learn better when we are asked to apply that knowledge regularly.

Math Talk

Number sense related questions lead to great math discussions. The more open ended you can make a question the better. Open ended tasks increase discussion and collaboration amongst your students. Encourage your students to work in groups or pairs so they communicate their mathematical reasoning.
