Year 4 - Number and Algebra
Standard 4.OA.1.1 - Express numbers in words.
Included Skills: Counting
Number and place value • Investigate and use the properties of odd and even numbers - using the four operations with pairs of odd or even numbers or one odd and one even number, then using the relationships established to check the accuracy of calculations • Recognise, represent and order numbers to at least tens of thousands - reproducing five-digit numbers in words using their numerical representations, and vice versa • Apply place value to partition, rearrange and regroup numbers to at least tens of thousands to assist calculations and solve problems - recognising and demonstrating that the place-value pattern is built on the operations of multiplication or division of tens • Investigate number sequences involving multiples of 3, 4, 6, 7, 8, and 9 - recognising that number sequences can be extended indefinitely, and determining any patterns in the sequences • Recall multiplication facts up to 10 � 10 and related division facts - using known multiplication facts to calculate related division facts • Develop efficient mental and written strategies and use appropriate digital technologies for multiplication and for division where there is no remainder - using known facts and strategies, such as commutativity, doubling and halving for multiplication, and connecting division to multiplication when there is no remainder
