Count Objects to Twenty and Number Sequences to One Hundred

Before you begin

• Say number words through ten; point to a drawing.
• An adult can read unfamiliar number names using the supplied 1–100 strip; memorization through one hundred is not required to start.

Choose by skill rather than age alone. Read with an adult when useful, revisit a lesson, or explore another grade.

Review and transfer

After the lessons, try 4 new review cases and a practical task. Each answer has an explanation and a link back to the related lesson.

Guest answers are temporary. Keep your own paper or document; this unit does not certify completion or record a school grade.
