You can track your child’s reading progress from the ‘Reading tab'. To gain a better understanding of the colour wheel check out this information released by the Ministry of Education.
[Please note, I post the whole classes reading levels so children can track their own progress. Each child learns and develops at different stages, please do not compare your child to other children. Instead do as much as you can to support and encourage them. Talk about what their goal is and where they want to reach.
