A great way to practice math at home would be simply counting to 100.  Also, finding shapes around the house would be a great way to practice shapes. You can have your child go on a "shape hunt" and find something that is a circle, square, rectangle, or triangle.  Or look for 3D shapes such as a sphere, cylinder, cube, or cone.  

 I have also added links for some great songs available on Youtube to help your child practice these skills!
