Unidades, decenas e idea aplicable para centenas. Constructing Numbers . . . An Independent Self-Correcting Place Value Station

Roll 2 dice to make a number, draw it, and write how many tens and how many ones -- kids love it! 4 different levels, this is easiest one:)

For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or eduation. (Common Core K.OA.4) | Operations & Algebraic Thinking | Learnist

These are place value posters for teen numbers. They were very useful in my class this year. There are some other ideas on this page as well.

Great way to help kids visualize (and remember!) the difference.

Place value die... a cube for tens and ones. Can easily be extended for larger numbers... hundreds, one thousands, ten thousands etc
