Learning the concept of numbers being written as words can be a little complex for a young mathematician. Being able to connect number words to numerals to values can be hard.
My mom drew a sheet like this for my Grade 1 son when he was struggling and it made a huge difference in him being able to recognize and understand which numbers belong to which words. We kept it tucked into his math workbook to reference when needed.
Simple, but effective, this handy little reference sheet helps kids to see how words and numbers are connected. Pop it into a page protector (or laminate it!) to keep it longer.
