Just cut out your aphids and your ladybug cards then count out the aphids and place them on the picture with the correct number. For example: place the picture card 5 in front of you then count out 5 aphids that the ladybug can eat.
I enjoy incorporating other subjects into my activities such as math and Science or reading and science. Its a great way to get in all the needed Core Standards. You can also use the Ladybug cards as flashcards. Have fun learning.
