Selection Sort Algorithm Activity | Hands-On Sorting Algorithm Lesson
Bring sorting algorithms to life with this lively, kinesthetic activity that keeps computer science front and center. Students embody the selection sort algorithm with manipulatives, action, and sequenced steps. Ideal for middle school and high school computer science or STEM class, this activity makes algorithmic thinking memorable through physical object-to-object comparisons and sorting. What's Included: 5 pre-built number lists (arrays) ready for student use Cut-and-use manipulatives (number

Multiplication Matching Cards
Set of cards which include multiplication algorithms and answers. Good practice for multiplying 2 and 3 digit numbers. (No calculator should be used)
1. Print off and cut out. (Cards need to be shuffled as the matching cards are next to eachother in the word document)
2. Place face down on a table and turn over 2 cards at a time. 3. Student who has turned the cards over needs to figure out if the two algorithms are equal. If they are, the student keeps them and has another turn. If not they are

Two Digit by Two Digit Multiplication Worksheet
This is a 20 question worksheet.
Questions 1-10 are meant to be solved using expanded algorithm (arrays, area models and place value charts are suggested in the directions)
Questions 11-20 are all two digit numbers multiplied by multiples of ten. These are meant to be solved using the shortcut method.
I use this worksheet as a review for these strategies before teaching my fourth graders standard algorithm.

MCC.3.NBT.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
This is a CFA pr/post test I created for the standards above. I give the test at the very beginning and then give the post at after I teach the unit.

Distributive Property Investigation
This in-class activity is meant for small groups or partners! It requires the students to investigate into what the distributive property entails when working with whole number multiplication (pre-algebra). The students will work together to discover the algorithm; therefore, creating a deeper understanding conceptually. The teacher's role is to guide and scaffold for the students to check their understandings.

Calcul Mental: Theory, Examples, and Worksheets(5th grade level)
Calcul Mental (Mental Arithmetic) is an instructional method used in France for developing computational skills in the context of a mathematically sound theory of arithmetic. The goal is for students to acquire, at each grade level, not only the age-appropriate computational skills, but the mathematical reasoning embedded in them. In particular, the computational algorithm must be consistent with, and indeed illustrate the underlying theory. In short,it prepares the middle school student for
