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

Boom Cards Adding 2 Digit Numbers With & Without Regrouping with Base Ten Blocks

Students use the strategy of moving infinite piles of base ten blocks provided on each card as they add 2-digit numbers. ❤️ Students determine if regrouping is required by checking to see if they have more than 10 ones in the ones section. ✅ If so, they drag ones to make another group of 10. ✅ They also show their knowledge of the algorithm by "carrying" the one to the top of the tens column if necessary. ✅ 20 Cards are self-checking and shuffle each time the deck is played. ✅ An int

Many of our students see numbers in a very rigid way. These “Can you make it?” activities allow them to explore numbers by composing and decomposing multiple ways! These divergent thinking activities are also called “low floor and high ceiling” tasks. This means, some students may choose quite simple equations to compose a number, while other students will reach more complicated, multi-step algorithms. That makes easy, no-prep differentiation! My students love these challenges! Their enthusiasm
