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.

Pirates vs. Vikings: Addition to 150
If you want to get your kids excited about practicing addition, then have them pick a side: Pirates vs. Vikings! I designed this activity to engage students while deepening their understanding of number sense, without using the standard algorithm. It can be used whole group, small group, or as a math station with a partner. Also, you could ask kids to use mental math strategies, use scratch paper, or allow them to rewrite the problems - the choice is yours!
I plan on making a companion product,

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
