Apart from the algorithm that requires splitting a number according to place value, there are many more strategies that

Subtracting 3-digit numbers using base 10 blocks, 100 grids, number lines, expanded form, mental math strategies, and more. Subtracting 3-digit numbers in grades 2 and 3 takes time for many students to master, especially when regrouping is required. Establishing a good understanding of place value is necessary before moving on to operations. Base 10 blocks are great for understanding place value and for simulating subtraction. Representing numbers with base 10 blocks allows students to see the

Mental Math Strategies for Addition and Subtraction with visuals. Compensating, decomposing, balancing, and clustering. Teaching Mental math Strategies to students even in grades 3 and up is very important as it develops their flexible thinking and boosts their confidence in math. Being able to use the addition and subtraction properties to apply mental math strategies shows a deep conceptual understanding that will, later on, be applied to more advanced concepts. Some students discover menta
