In our math class, students spend time discussing problems in depth and are asked to share their reasoning and solutions. It is important that your child solve math problems in ways that make sense to him or her. At home, encourage your child to explain the math thinking that supports those solutions. Please look for more information and activities about Fraction Cards and Decimal Grids that will be sent home in the coming weeks.
