Use these hands-on one more one less activities to strengthen number sense skills in preschool and kindergarten.
So your kids have learned to count. Maybe they can count to 10, 20…even 100! Does that mean you’re done teaching them the math skills they’ll need?
Of course not! Learning to count is just one small step on the path to mathematical understanding, or number sense. Developing number sense is a key focus throughout the early years and beyond, and the process includes a variety of skills.
In this specific article we’re going to take a look at one of these skills, understanding one more and one less. Although this seems obvious to us as adult learners kids can often struggle with this concept, particlarly one less. Providing them with many concrete experiences with hands-on materials can lead them to a deep understanding of the concept, and this will support them later on as they need to rely on the concept of one more and one less to do more complex math problems.
WHAT IS NUMBER SENSE?
But first, you may still not have a clear picture of number senses and why it’s important. This video from Build Math Minds gives a good overview.

ONE MORE ONE LESS ACTIVITIES ON FANTASTIC FUN AND LEARNING
The great thing about one more one less activities is there are many opportunities to naturally weave them into your daily routines if you are intentional about it.
Here on Fantastic Fun and Learning I’ve outlined a series of three hands-on activities you do with any small items (math manipulatives).
Once you learn the simple steps and the math talk that goes along with the activities to deepen the learning potential, then you can also duplicate the same activities with things like snack items and small toys your child plays with throughout the day.
ONE MORE ONE LESS MATH GAMES
As kids beging to understand the concept of one more and one less we want to help them develop fluency and be able to quickly identify one more and one less without having to give it a lot of thought.
At this stage playing fun one more and one less math games can help kids develop that fluency.
