By the end of 4th grade, students should be able to apply their understanding of place value and properties of operations to multiply a whole number of up to 4 digits by a one-digit whole number and multiply two two-digit numbers and then illustrate and explain their thinking using equations, arrays and/or area models (MAFS.4.NBT.2.5)….but we know that students access standards at varying levels, and it can sometimes be tricky to pinpoint where that is exactly. This video clip can provide you with some insight on where your students are at in the progression of multiplication, so that you can respond with instruction that builds foundational understanding they may be missing, or help students make connections so that they can move forward along the progression.
