Ask a six-year-old what the 7 in 78 means, and the answer is often just « seven ». Knowing that it stands for seventy takes time. This 1st grade tens and ones to 99 worksheet gives that idea a simple routine. Twelve boxes each show a number followed by two dotted lines, one for tens and one for ones. The first box is done as an example, so your child sees that 52 splits into 5 tens and 2 ones. The other eleven range from 3 to 99. Several numbers end in zero, and two have no tens at all, so each box asks for real thought. A second page gives the answer key.
