Students in Miss Curley’s third-grade class used place value blocks to model and solve 9×30 by building groups of tens. First, they represented 30 as three tens. Then they created nine equal groups to match the 9 in the problem, laying out three tens in each group. As students combined and counted the blocks, they saw that 9 groups of 3 tens equals 27 tens. They recorded this as 27 tens = 270, making the connection from concrete manipulatives to the written equation. This hands-on strategy, aligned to benchmark NSO.2.3, helped students understand how multiplication relates to place value and … Read More
