As children become more confident in their math skills, give them worksheets one grade level above their current grade. Help them if necessary, but when students become successful in the upper level workbooks; their confidence will really improve. The seed will be planted early and parents can watch as it grows.
I have observed teachers who really challenge their students to achieve higher order thinking These teachers take their students as early as the Second Grade and teach them how to add, subtract, multiply and divide using only their bran. We call this Mental Math. When I observed a Second Grade Class that had their students mentally answering math computation questions, I put my own son in that class. Shortly after being enrolled, He, too, learned how to do Mental Math. From that point on, math was my son's best subject. Teachers can really make a difference and parents can help affect change.
These worksheets are provided for all subjects present in a 1st grade school curriculum covering English, math, science & many others. Worksheets are also provided for developing & nurturing the thinking skills of a student too in the form of crossword puzzle & thinking skill worksheets. Moreover, many 1st grade worksheet providers as well provide time counting & calendar worksheets as well to test the IQ of the kids.
Parents who are positively involved with their children and want the best for them will make sure their children are keeping up with their math skills and are successful in school.
