Numbers about me! love this FREEBIE for the first few days of school! Cute, but need to add some questions to get to higher numbers. Then trade number chart with partner and have them answer questions to get to the original number.
Kindergarten Author Study: Clement Willems - would be cute to do the reverse and have the first day with all the days of the school year and take on off for each day, like a count down instead of a count up!
Here's a nice post on using place value cards to help students understand decomposing numbers and expanded form. Includes a link to a set of place value cards. Could change colors to go with Math-U-See.
