Divide a 2-digit by a 1-digit number using partitioning and representations (no remainders)

Maths

In this unit pupils will divide a 2-digit and 3-digit number by a single-digit number using partitioning and representations with exchanging and remainders. They will divide a 2-digit number by a single-digit number using short division. In the future unit pupils will  use their knowledge of multiplication and division to solve comparison and change problems.

In the prior unit pupils interpreted a division story with a remainder and represented it with an equation. They explained how the remainder related to the divisor. In this unit pupils will divide a 2-digit and a 3-digit number by a single-digit number using partitioning and representations and divide a 2-digit number by a single-digit number by using short division.

Division by partitioning leading to short division (2 and 3-digits by 1-digit)

The process of unitising and exchanging between place values.

Divide a 2-digit by a 1-digit number using partitioning (with regrouping)

A remainder is an amount left over after division.

The process of unitising and exchanging between place values is known as regrouping.

Divide a 2-digit by a 1-digit number using representations with exchanging and remainders

Short division is a formal method of division often used when dividing any number by a one digit number.

The dividend is the amount that you want to divide up.

A divisor is a number that divides the integer exactly (no remainder).

A quotient is the result after division has taken place. 

Divide a 2-digit by a 1-digit number using short division (no regrouping )

Divide a 2-digit by a 1-digit number using short division (with regrouping)

A remainder is an amount left over after division (happens when the first number does not divide exactly by the other).

Divide a 2-digit number using short division (with regrouping and remainders)

The dividend is the amount that you want to divide.

A partial quotient is seen when the dividend is partitioned.

Partition means splitting an object or value down into smaller parts.

A quotient is the result after division has taken place.

Divide a 3-digit by a 1-digit number using partitioning and representations (no remainders)

Partition means splitting a number into parts.

Divide a 3-digit number using partitioning and representations (one regroup)

Divide using partitioning and representations (multiple regroups and remainder)

Divide a 3-digit by a 1-digit number using short division

A remainder is an amount left over after division (it happens when the dividend does not divide exactly by the divisor).

Divide using short division with regrouping and remainders

Use short division when the hundreds digit is smaller than the divisor

Is a formal method of division often used when dividing any number by a one digit number.

Partition means splitting a number into smaller parts.

Use efficient division strategies to solve problems

The basic idea of multiplication is repeated addition.

Division is splitting into equal parts or groups. It is the result of "fair sharing".

Inverse means the opposite in effect. The reverse of.
