For fractions with different denominators, find the least common denominator to convert the fractions before adding or subtracting the numerators.
Learn Your Times Tables
The document introduces times tables and explains why students need to memorize them. It notes that to do algebra, students must know answers like 3 x 8 = 24 without counting. It then begins explaining the 2 times table, showing 2 x 2 = 4 and using apples to demonstrate that if you have 2 apples and another 2 apples, you have 2 + 2 = 4 apples total. The purpose is to illustrate multiplication and how remembering times tables is essential for algebra.
Number – place value
Numbers represent quantities and are made up of digits 0-9. A digit is any of the ten symbols used to form numbers of any size. The place value system uses these digits in columns with increasing place values to write numbers. The value of each digit depends on its place in the whole number. Larger numbers are written with digits in columns representing thousands, hundreds, tens and units with zeros as place holders when the value is zero.
Factors & multiples
The document discusses factors and multiples of numbers. It defines factors as the numbers that multiply together to get a product. It provides examples of finding all the factors of several numbers by trying all combinations of multiplying smaller numbers. It then defines multiples as the results of multiplying a number by the counting numbers 1, 2, 3, etc. It gives examples of listing the multiples of 4. Finally, it briefly introduces prime and composite numbers, with prime numbers only having two factors and composite having more.
Subtraction Using Partitioning
This document describes the method of subtraction using partitioning. It explains that partitioning involves splitting the smaller number into place values like tens and ones and then subtracting place values one at a time, starting with the largest place value. It provides an example of subtracting 86 - 47 by first subtracting the tens (86 - 40) and then the ones. It also demonstrates how this method can be used for larger numbers by splitting the smaller number into hundreds, tens, and ones.
Number bonds

It provides examples of multiplying numbers like 2 x 3 and 3 x 2 by representing the numbers as groups of objects and counting the total objects. The document also demonstrates how to multiply two-digit numbers by multiplying the digits in the ones and tens places and regrouping or carrying numbers to the next place value.
DIVISION
Division is one of the four basic mathematical operations. It involves splitting a number, called the dividend, into equal groups determined by the divisor to find the quotient. For example, in the division problem 63 ÷ 9, 63 is the dividend, 9 is the divisor, and 7 is the quotient. Division is the opposite of multiplication, so knowing one fact allows determining the other. Division can be written horizontally or vertically using the division symbol ÷.
Decimals
The document discusses decimals and their relationship to fractions. It explains that decimals extend the place value system to include values less than one. The value of each place decreases by a factor of ten as you move to the right of the decimal point. Decimals can be added, subtracted, multiplied and divided using standard algorithms. Terminating decimals can be converted to fractions by writing the decimal as the numerator over an appropriate power of ten as the denominator. Repeating decimals can be converted to fractions by writing the repeating portion as the numerator over nines and zeros in the denominator.
