This week, we have continued learning our 3 times table through Supermovers and Times Table Rockstars. We have been using the distributive law to help us to write our multiplication number sentences in lots of different ways.
4 groups of 3 + 3 groups of 3 equals 7 groups of 3
(4 x 3) + (3 x 3) = (7 x 3)
Also, we have found that we can use our known facts to help us work out other multiplication calculations.
(3 x 3) = (2 x 3) + 3
At the beginning of the week, we moved onto dividing by 3 by grouping and sharing which we were then able to apply to solving word problems. Towards the end of the week, we learned about fact families.
If I know 3 x 4 = 12
Then 4 x 3 = 12
12 ÷ 4 = 12
12 ÷ 3 = 12
Finally, we revised multiplying by 10 using our place value knowledge to help us make a generalisation. We can now multiply any number by 10!
This week we have been applying our knowledge of our 2, 3 and 5 times tables to solve trickier multiplication calculations. Also, we drew on our knowledge of distributing and our special power of being able to multiply any number by 10 to help us with these calculations.
19 x 5 = (10 x 5) + (9 x 5)
17 x 3 = (10 x 3) + (7 x 3)
This week, we continued to use our known facts and our special power of being able to multiply any number by 10 to support us when multiplying two digit numbers by one digit numbers.
15 (5 x 3)
60 (20 x 3)
We also used a stem sentence to help us explain how we knew that 20 x 3 = 60.
If the calculation is 10 times bigger, the answer is 10 times bigger.
Later in the week, we moved onto solving division word problems using pictures alongside our written calculations. We learned 3 new mathematical words which we can confidently use.
24 ÷ 2 = 12
This week, we moved onto solving division word problems. We were able to use both drawing and our times table knowledge to help us with this. By the end of the week, we have been able to confidently solve problems involving remainders.
We are looking forward to sharing our new mathematical knowledge from this half term with you at our parent outcome next week!
This week, we started our new fractions unit. We focused on the relationship between the part and whole in a variety of familiar contexts.
If Europe is the whole, then the UK is part of the whole.
If the school is the whole, then Year 3 is part of the whole.
Next, we focused on identifying equal and unequal parts of shapes.
