The stages are progressive and to move on to the next stage, it is important to have a firm grasp of the previous. That being said, stages can be repeated to help embed the skills. This should not be seen as a failure, but rather allowing learners to progress at their own pace. This is similar to the way schools revisit key concepts each term.
It is expected that an adult attend the lesson with each child. Children should practice 3-4 times a week for around 10-15 minutes to reinforce the skills and considering the age of the learners, they will need to do that with an adult. In the beginning, there’s not much to practice and a quick 3-5 minutes may be sufficient. Remember that it’s more about establishing the habit of daily practice rather than drilling in 10 minutes of Hot Cross Buns until everyone in the household is unhappy! If you’re joining the Dots & Squiggles programme (not the Pre-School programme where there is greater flexibility) it is important to commit fully to the times as it may be tricky to catch up.
