In maths, my group created a DLO about algorithm addition with decimals. We learned how to line numbers up correctly using place value and decimal points so the equation stays accurate. We also learned that adding a zero as a placeholder can help make decimals easier to solve.
In our example, we added 51.40, 80.60, and 38.75 together using the vertical algorithm method. First, we lined up the decimal points and place values carefully. Then we added each column one at a time, starting from the right. When the total was more than 10, we carried the extra number to the next column. Our final answer was 169.75. This activity helped me understand how important place value is when working with decimals. It also helped me become more confident solving decimal equations and explaining my maths thinking clearly.
