These worksheets are specifically designed for Grade 1 students to help them learn and practice counting by 10s within the range of 10 to 100 and 10 to 200. The sheets are organized in a clear, easy-to-follow layout with numbers strategically placed to allow students to draw connections and fill in the missing sequence. As they progress from 10 all the way up to 100, they reinforce their understanding of this fundamental math concept. The fun illustrations at the bottom add a playful element to the learning process, making it an enjoyable activity for young learners to improve their numerical skills.
