Lots of variety here. Print two copies of the hippo page and two copies of the /l/ words page. Cut out hippos into cards, and glue a word on the back of each picture.
1. Play a matching game! Have your child say the /l/ word two times each time they flip a card over, and when they get a match they say it 5-10 times.
2. Play Go Fish with the cards, and when they get a match they have to say the word 5-10 times. If you get a match, have them still say it 5-10 times to get the practice.
3. Hide the hippos, and have your child "look" for them. Give directions, "look under the table" or "look on the couch." Emphasize the /l/ sound. Take turns hiding and giving directions.
