Encourage your kids to learn geometry! Remind them that when shapes are cut into two equal parts, they are called halves. Have them look at the circles in the worksheet, and trace the lines that cut the circles in half. Geometry is an essential part of education, and although it may not be exciting, it's a valuable skill to have.
Help your kids learn fractions! Even if they're not eager, teach them as they get older. Teachers will provide enough lessons and homework, but you can go a step further. Look at a worksheet with your kids and help them circle the piece that would make the pie whole.
Explain to your students that they can make a new shape by combining halves, thirds, and fourths of a shape. Show them the worksheet with the rectangle at the top and ask them to find which sets of halves, thirds, and fourths make it. Have them check all the correct sets.
