Boom Cards Subtract 2 Digit Numbers With & Without Regrouping Using Algorithm
Students demonstrate their knowledge of the subtraction algorithm as they subtract 2-digit numbers with regrouping. ❤️ Students drag the regrouping marks and type the new number of ones and tens into the red boxes. ✅ Next, they subtract the columns and type their answer in the green box. ✅ 20 Cards are self-checking and shuffle each time the deck is played. ✅ An interactive game for iPad, computer, SmartBoard, or projector. ❤️ How about a Boom Cards Math Center? ❤️ Cards are self-correcting

Napier's Bones - A Manipulative for Understanding the Multiplication Algorithm
SMARTBOARD presentation outlining the history and development of Napier's Bones, also known as Napier's Rods, which are used to help students understand the algorithm for multiplication. Students can manipulate the digital 'rods' given in the presentation. Using the directions given, students can also make their own rods for personal use to solve multi-digit multiplication problems. Connecting Napier's Bones with lattice multiplication is another way to transition students to doing the traditio

Grade 4 Math in Spanish 4.NBT.B.5 Multiply 2x2 Traditional Algorithm
This Smartboard lessons covers the multiplication of 2-digit numbers using the traditional algorithm. If you are a GoMath user, it corresponds to Chapter 3 Lessons 5 and 6.
If you are NOT a GoMath user - congratulations! haha! I didn't care for their projectable content, so I made my own. Hopefully this can be a time-saver for you as well.

Pupils need to be able to work efficiently and confidently when calculating. Using standard algorithms isn’t always the most efficient way to calculate an answer. Rather, pupils use to need number sense to decide what is the best way to carry out a particular calculation and then use estimates to check whether their answer is reasonable.
