If your child gets stuck at along word, they develop a discouraging attitude, involuntarily. That is why it’s better to start with concepts like CVC.
That encourages and motivates them to learn more. It saves you a lot of tantrums as well. If you instill it in your child’s mind from the start that they will get a reward for behaving nicely.
For kids these days, the best way to teach them is to use digital learning applications. They enhance their concentration span for a specific concept. The enticing animation and vivid graphic. They don’t let your child lose attention out of sheer boredom.
The learning apps these days, come with a game-based interface. My point is, your child solves the worksheet thinking it’s a game! It’s hitting two birds with one stone!
