Adding Strategies 2,4,5,6 : These skills are on the Grade 3 curriculum, but they may be used at any level. For instance, looking for the gap between the given numbers and a self-determined "centre" is the concept of absolute value on the Grade 10 curriclum. The vertical algorithm format here is for these younger grades. Answers are given in the format of the questions so that the student will see all the work that's needed and where he might have gone wrong. The skills of making pictures a

These two units Going Shopping1: Counting and Evaluating Money and Going Shopping2: Spending Money are practical applications of various expectations on the Grade 3 Math curriculum in British Columbia, Canada. There is information about the Goods and Service Tax and the Provincial Sales Tax in terms of adding them into the cost of an purchase, but the student is not required to calculate the percentage. This information would also be useful for adults who are new to Canadian money too. If you

This Lesson in borrowing from the tens column uses Canadian money a) because I am Canadian in Canada and b) because our money denominations are clearly different from one another. The lesson demonstrates the action in objects (pictured dollars) and in equation format and in the traditional algorithm to appeal to children who are able to understand only one or two or all three of those methods of demonstrating the concept of subtracting with borrowing. Demonstrations by the teacher and student

Some children understand regrouping in number-sentences. Some must handle money to understand carrying/borrowing conversions. Some can follow flowcharts best. This flowchart is designed to assist with any subtraction example up to 999 with or without borrowing. The number facts are included for those who have trouble remembering them, and they are surrounded by the symbol for a document containing data as back-up for the data calculation step in the parallelogram. The colour scheme of the t

There are many children who very vague concepts about numbers. Although the work level is for Grade 3, you may find older students without these words or concepts. One of the students' performance tasks is to explain what they are doing. These worksheets are to give them the words to do that explaining for adding and subtracting. Each section is repeated. The first copy is to read and discuss. The second copy is for filling in the blanks. minuend "that amount to be diminished", subtrahend

For those who find flowcharts easier to follow than a list of steps, this flowchart shows the repetition of steps. One can follow the green arrows for a simple addition with no carrying, or taking the detours following the blue arrows until it goes back to the basic process.
