Algorithms
What are some everyday algorithms?
Recipes, assembly instructions, procedures in owners' manual, morning routine
What is the most important tool for the development of algorithms? "Fluency with basic facts
Speed and efficiency
Base ten blocks are also called?
Dienes blocks
True or false: The term carrying is mathematically correct in addition
FALSE
*Regrouping
Aka the expanded algorithm, intermediate traditional algorithm, instructional algorithm, and what?
Partial sum algorithm
Very similar to the expanded/intermediate traditional algorithm in which the organized structure helps with place value alignment and involves and rectangular table with 1 direction diagonals
Lattice addition
The following are steps for which algorithm?
1. Write addenda vertically
2. Add vertically (basic facts) and record one's digit below the diagonal and the tens digit above
3. Add the alleys from right to left regrouping to the next alley as needed (must s
Lattice addition
True or false: The term borrowing is mathematically correct in subtraction
FALSE
*Regrouping
List the three alternative subtraction algorithms.
1. Subtract from the base
2. Equal addends
3. Alternative traditional
The "use what you have" algorithm of subtraction
Subtract from the base
The goal of this algorithm is to find an "easy" subtrahend that does not require regrouping (multipliers/powers of ten)
Equal addends algorithm
An algorithm that goes to the minuend to regroup and adds one to have enough to subtract
Alternative traditional
