In this math video we will learn how to subtract rational numbers that are decimals. We will begin by review how to subtract decimals using 3 easy steps. Step 1 - Line up the decimal points vertically. Fill in any 0's where necessary....

Pupil outcome: I can use short multiplication to record regrouping from the 10s to the 100s Key learning points: - If the product of the single digit and the tens number is greater than 100 then you regroup ten tens into one hundred. -...

Pupil outcome: I can divide using short division with regrouping and remainders. Key learning points: - If the hundreds number is not a multiple of the divisor then the remainder is regrouped for tens. - If the tens number is not a...

Pupil outcome: I can use column subtraction with regrouping from the tens to ones. Key learning points: - Regroup when the ones digit of the subtrahend is greater than the ones digit of the minuend. - Regroup a ten into 10 ones. - Change...

Pupil outcome: I can use short division when the hundreds digit is smaller than the divisor. Key learning points: - If the hundreds digit is smaller than the divisor then it is exchanged for tens and included with the tens digit - If the...

Pupil outcome: You can divide a 3-digit by a 1-digit number using short division Key learning points: - Division of a 3-digit by a 1-digit number can be organised with short division. - The partial quotients are recorded above the...

Pupil outcome: I can explain how to use long multiplication to multiply a 4-digit by a 2-digit number. Key learning points: - Calculate the partial products. - Add the partial products to recombine. - Regroup when numbers bridge 10, 100,...

Pupil outcome: I can compare and order mixed numbers when the whole is the same. Key learning points: - If mixed numbers have the same whole number parts, then the size of the fractional parts determines the greater number. - When we...

Pupil outcome: I can divide a 2-digit by a 1-digit number using short division (with regrouping and remainders). Key learning points: - If the tens number is not a multiple of the divisor then the remainder is recorded next to the ones...

Pupil outcome: I can compare and order mixed numbers when the whole and the numerator of the fractional part is the same. Key learning points: - If mixed numbers have the same whole number parts, then the size of the fractional parts...

Pupil outcome: I can round integers to one significant figure. Key learning points: - It is possible to use rounding and place value to know the size of a number without knowing the actual number. - The first non-zero digit of a number...

Pupil outcome: I can use column addition including regrouping ones. Key learning points: - When using column addition, start by adding the numbers with the smallest place value first. - If the sum of the ones digits is ten or greater,...

Pupil outcome: I can generalise and fluently use addition and subtraction strategies to calculate with fractions and mixed numbers. Key learning points: - To make the denominators the same, you may need to scale up or down. - It can be...

Pupil outcome: I can use column addition to add numbers by regrouping tens. Key learning points: - When using column addition, start by adding the numbers with the smallest place value first. - If the sum of the tens digits is ten or...

Pupil outcome: I can add 2-digit numbers using column addition. Key learning points: - The addends are written in columns with the same value digits in the same column. - Start by adding the numbers with the smallest place value first. -...

Pupil outcome: I can order a set of 3-digit numbers. Key learning points: - If the 100s digits are different, the numbers can be compared or ordered by looking at the 100s digit. - If the 100s digits are the same, the numbers can be...

Pupil outcome: I can explain how the distributive law can help to solve multiplication problems more efficiently, and write equations that show this. Key learning points: - 2 groups of ___ plus 3 groups of ___ is equal to 5 groups of ___...

Pupil outcome: I can find the missing addends when adding two-digit numbers. Key learning points: - Two-digit numbers can be partitioned to help find a missing digit or a missing addend. - One equation can be used to help solve another...

Pupil outcome: I can use strategies to make solving calculations more efficient. Key learning points: - Equivalent calculations can be used with the same difference or same sum to make calculations ‘easier’. - A number line can be used...

In this video, students learn how to multiply and divide by multiples of 10 by moving the decimal point. The teacher explains the concept of multiples of 10 and the base 10 system. Using examples and a place value chart, the teacher...
