When your child is learning to read, looking for patterns in words is huge! If they know the word, “at” for example, then they know all the words that can be made by putting a consonant in front of it, cat, rat, mat, you get the idea. Once they understand blends, they can also read those, that, chat, slat. All these words make up one big happy family, the -at family! Other common word families that are good for your child to know are: -og, -en, -ack, -ig, I could keep going. You can go to Mrs. Alphabet and see a list of more. Word families are good rhyming practice and naturally make writing easier too.
When teaching word families at school, we drew a house and gave it a family name, like the Acks! Then we would write “family members” inside the house.
You could take it a step further and add words with blends.
You can also have them illustrate a picture of the words, ahem, I mean family members!
I also used to read, Flip the Page Rhyme and Read books to the kids to work on word families/rhyming. It’s a great series with Zug the Bug and Tog the Dog. You can also make your own, as Having Fun at Home did. Get your kids involved and this could be a great learning activity that is also FUN!
