Take your kids to the supermarket and ask what they're looking forward to buying. Help them solve the three questions in the worksheet by interpreting each one into an equation, then choose the right answer.
Read the Earth Day-themed word problem aloud to your kids, pointing to the pictures as you go. Use the number line to help them count on and find the answer. Then check it together. Doing this can help them learn more about Earth Day and meet other children who are doing their part to keep it clean.
