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

Regrouping Template for 2 - 3 - 4 Digit Addition or Subtraction
Regrouping Template for 2 - 3 - 4 Digit Addition or Subtraction Description : The standard algorithm for addition and subtraction is a fundamental skill that students must learn. However, we know teaching and mastering this skill can be tricky! To make the process easier, these anchor chart templates have been created for 2 digit, 3 digit, and 4 digit addition and subtraction. The anchor chart templates provide a visual representation of the steps involved in the standard algorithm. The template

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

NUMBER SENSE "Can you make it?"
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
