Normally I'm not used to teaching about contractions so early in the year, but my 2nd graders were ready for it and it fit right along with our guided reading texts, so we dove in last week, learning all about contractions! Most of these ideas I found on Pinterest, so I'm not claiming these ideas as my own, but they did work super well in helping my friends understand contractions. :)
First we made an anchor chart and each day repeated "A contraction has an apostrophe that takes the place of letters you see." It's a nice little rhyming sentence which helped my friends catch on quickly. We then made contractions out of the various examples at the bottom for practice taking two words and turning them into the shorter form.
Have a great day!
