## Counting by Tens Matters: A Next Step in Place Value Understanding

How can you help your primary students make the leap from working with small numbers to becoming fluent with larger ones? One way they can start thinking in larger ‘chunks’ is by counting by tens. More than just an oral exercise, counting by tens is an essential skill that builds number sense, encourages thinking about number structures, and economizes counting and operations. Students with a strong conceptual understanding of round numbers, a ‘ten’, and ‘the tens place’ are better prepared to work with two-digit numbers and beyond. In this post, we will share the ideas behind our exercises in the topic Counting by Tens and some additional tips on reinforcing counting skills using Unifix cubes…

## How to Teach Early Numeracy Using the Number Line

While cubes and other manipulatives support learning by representing numbers, the number line actually develops learning by giving students another look at number relationships. Your primary students may find using a number line more challenging for some concepts. However, it’s important to stick with it as number lines provide learning opportunities for later skills that can’t be replicated with cubes, such as negative numbers, decimals, rounding and graphing.

That’s why at Happy Numbers we include the number line early and often throughout our exercises. In this post, we’ll share some of these activities that you can use with your class at different stages of learning…
