In this packet, I have included 10 pages of different practice problems on the concept of figuring out the problem with traditional multiplication and checking it with the lattice method. In other words, each page looks similar, but has different problems. This makes it easy to give out for an assessment and promote students doing their own work or give out extra pages for extra practice.
I used these with my 3rd grade tutoring group, but it also touches on the 4th grade standard, 4.NBT.B.5, and can be used with older grades, as well.
