Happy Numbers includes several language-based math lessons that are especially helpful for ELLs and early readers. These include shape names, position/direction vocabulary (such as above, in front of, down), and comparison vocabulary (taller, smallest, greater than). Students also learn to read written numbers and match written names to numerals. Our audio feature allows students to hear any text read aloud in a clear, natural voice. A Spanish version of the system is also available.

Placement test in all the grades and Prekindergarten curriculum have an automatic voice over available. In other grades students need to click on the microphone to hear the directions on the screen read aloud.
