Math
Victoria used a place value chart to practice multiplying 3-digit numbers by 10, which helped her see how each digit changed position when the value was expanded by a factor of ten. She learned that multiplying by 10 shifts digits one place to the left in the place value system, turning hundreds into thousands, tens into hundreds, and ones into tens. By working with a visual chart, Victoria strengthened her understanding of how place value supports multiplication, not just memorized a rule. This activity likely helped her build confidence with larger numbers and made the pattern of multiplying by 10 easier to recognize and explain.
Tips
To deepen Victoria’s understanding, she could practice multiplying more 3-digit numbers by 10 using a place value chart and then explain each digit’s movement aloud. She could also compare multiplying by 10, 100, and 1,000 to notice how the number shifts differently each time. For a hands-on extension, she could create her own set of number cards and sort them into place value columns before and after multiplication. A quick challenge would be to write several equations and match each one to its correct product, helping her connect the visual chart to mental math.
