Mathematics
Gracie practiced multiplying whole numbers by 10, 100, and 1000, using the fact that each factor shifts the digit sequence one, two, or three places to the left. She applied the place‑value concept to see how adding a zero at the end of a number increases its magnitude tenfold, a hundredfold, or a thousandfold. By working through several examples, Gracie reinforced her mental‑calculation speed and recognised patterns in the multiplication tables. This activity helped her understand the relationship between multiplication and the decimal system.
Tips
1. Create a “Zero‑Race” board game where Gracie rolls dice, multiplies the landing number by 10, 100, or 1000, and moves the corresponding number of spaces. 2. Have her design a place‑value poster that visually shows how adding zeros changes a number’s size, then label real‑world examples (e.g., money, distance). 3. Introduce simple word problems that require scaling quantities up by factors of 10, 100, or 1000, such as budgeting for a school event. 4. Use an online place‑value interactive to let her experiment with moving digits and seeing the effect instantly.
