Please use these cards to assist your child/student in building their number sense. This will help them to do mental math. Make sure they are moving away from counting the individual dots and actually visualizing groups of ten and five, then counting on from there.
Be on the look out for more flash cards to build number sense.
As always, if you have any questions, comments, or concerns, please feel free to contact me via my blog at www.breyonecarter.com
