This activity is one of many components necessary for a quality early literacy curriculum. Say the sentence to your child, then have your child circle the correct object. Pay attention to enunciating the beginning sound (i.e. window would be said as w/w/window).
The Book Chart included is a great motivational tool for your child. Start each week by putting a circle on the chart to give them a goal to reach that week. Every time your child reads a literacy story, plays a game or completes an activity sheet they can put a sticker on the chart. You can give your child incentives if they meet their weekly goal.
