Place value has evolved since Common Core came around. It’s not just tens and ones houses anymore. The understanding between how hundreds, tens, and ones makeup and change numbers is what NBT is all about. NBT expands past place value, too. Within this domain, you’re using place value to add double and triple-digit numbers, compare two different numbers, work within a 100s chart, and more! I’m rallying up some fabulous ideas I have found from other teachers and old lessons that I have also taught for teaching NBT for 1st and 2nd
Learning the Hundreds Chart
The NBT standard in first grade has the students working with a 120 chart. They need to be able to move around the hundreds chart, knowing how adding tens and ones correlates with the numbers on the chart.

Here is a window activity that helps students quickly locate ten more and ten less than a number as well as one more and one less.
Chart Puzzle

This hundreds chart puzzle helps test students knowledge of numbers on a hundreds chart. Since the pieces are cut into different groups of numbers, students will have to use their place value brains to place the sets together.
Place Value with Base Ten Blocks
Hundreds, tens, and ones are best learned with place value blocks. Representing two and three-digit numbers with base ten blocks will really help in solidifying a student’s grasp on place value.

I love this activity where students use a tens chart and super-sized base ten blocks to represent a number.

Here are three different base ten activities using base ten blocks from my store!
Representing Numbers in Different Ways
Number names, base ten blocks, standard form, and expanded form.
So many ways to show a number! And all of these ways help students perfect their place value.

2-Digit Addition and Subtraction with Place Value
This is such a difficult topic to teach, but if you set up students with a firm grasp on place value, double and triple-digit math helps. We always start with adding tens. Base ten blocks help a TON when teaching. It helps tie together the lessons from place value and their new big skill.
First & Second Grade NBT Centers
My kiddos always called this the “T.” They felt very comfortable with this T. It helped split the problem up for them. Once we started working without it, they would write it on themselves. It took a while for them to get comfortable enough without the T, but by the end of the year, they were experts!
Here are my resources for Teaching NBT for 1st and 2nd.

Need it DIGITALLY?
I have created a few Place Value activities in ready-made Google Slides. These are for first and second grade.
