An odd number is any whole number that cannot be divided exactly by 2    The ones digit is 1, 3, 5, 7 or 9

Any whole number that can be divided exactly by 2 is an even number. The ones digit is 0, 2, 4, 6 or 8

Use patterns of odd and even numbers in the times tables to solve problems

Maths

In this unit pupils will represent counting in sevens as the 7x table explaining the relationship between adjacent multiples of 7 and knowledge of the 7x table to solve problems In the future unit pupils will explain how each part of a multiplication and division equation relates to a story They will partition one of the factors in a multiplication equation in different ways using representations

In the prior unit pupils will explain the relationship between multiples of 3 and multiples of 9 and use it to solve problems. In this unit pupils will represent counting in sevens as the 7x table explaining the relationship between adjacent multiples of 7 and knowledge of the 7x table to solve problems.

7 times table: odd and even patterns, square numbers and tests of divisibility

Which of these expressions will result in an odd product?

Without calculating, will this equation produce an odd or even product? 23 × 6 =

When two odd factors are multiplied together, the product is {{ }}.

Sofia thinks of a 2-digit number multiplied by a 1 digit number. Her product is even. What could the expression be?

True or false. All products with 52 as one factor will be even.

Jacob says, “When I multiply an odd factor by an {{ }} factor, the product will be even.” Complete the missing word.

In a multiplication equation, if one factor is odd and one factor is even, the product will be {{ }}.                            

Which expressions will give an odd product?

Multiply an odd factor and an even factor together.

Which of these times tables has all even products?

Which of these times tables have a pattern that results in the products alternating between odd and even?

True or false. The products in the 8 times tables will always be even.
