We are currently studying Area and Perimeter in math. You can work with your child with these skills by having them measure different rectangles and find the area/perimeter of each.
The math words they need to know the definition for are:
Area, Perimeter, square, rectangle, pentagon, hexagon, triangle, obtuse triangle, acute triangle, parallel and perpendicular lines
