Mathematics
Victoria used column addition correctly and showed that she could align numbers by place value to add them accurately. Because no exchanges were needed, she worked with sums where each column stayed under ten, which helped her focus on careful calculation rather than regrouping. This activity showed that she understood how to keep ones and tens in the correct columns and check her work for accuracy. It also suggested steady confidence and attention to detail while completing a standard written method for addition.
Tips
To build on Victoria’s column addition skills, she could practice adding slightly larger numbers that do require exchanges, so she can see how regrouping works when a column total goes over ten. A number grid or place-value chart could help her explain why each digit belongs in its column and why carrying happens. She could also complete a quick mental-maths warm-up before written work to compare mental strategies with column addition. For a creative challenge, Victoria could write her own addition word problems and solve them using column addition to show understanding in a real context.
