Eustls Mlddle School Rising 6thth Grade Summer Math Packet Our rising 6th graders had a busy year learning new math skills. Mastery of all these skills is extremely important in order t o develop a solid math foundation. Reinforcing concepts will be beneficial for your child. Each year builds upon the previous year's skills in math. Please have your child complete this summer math packet and return on the first day of school. Your child will be expected to know their addition, subtraction, multiplication and division facts up t o 12. Practice, practice and practice. Flash cards work great! After your child has completed the math problems and you feel your child is still struggling on a certain concept and needs further practice, you can visit some of the following web sites. Thank you so much for assisting your child with this packet. Have a wonderful summer.
