How to Learn Math Fast

How to Learn Math Fast
1) Find a tutor. Working one on one with a skilled teacher is the best way to quickly learn any subject.
2) Don't be afraid to ask for help. Figuring things out by yourself can be really interesting, but it is not very time efficient. If you get stuck, ask someone who knows what to do.
3) Use repetition. Every time you learn a concept, do several problems to reinforce that concept. For example, if you learn how to add fractions with common denominators, have your tutor or another adult come up with several problems involving adding common denominators.
4) Don't repeat too much. Doing five pages of dittos is probably a waste of time. Do enough problems to get the concept and drill it into your head a bit, but don't keep at it until your eyes glaze over.
5) Work on math every day. Setting aside a block of time every day to study math will help to keep the concepts fresh in your head, meaning that you have to spend less time reviewing.
6) Begin each day by reviewing a few recent lessons briefly. One of the biggest problems people run into when trying to quickly learn math is forgetting previous lessons and having to review basic concepts. By spending a few minutes every day reviewing, you can make sure that the mathematics you learn goes into your longterm memory rather than being forgotten after a couple days.
7) Use flash cards, mnemonic devices and other memory aids. Using flash cards is a great way to memorize your times tables, while mnemonic devices are a good trick for more complex concepts.
8) Use story problems and other, more difficult challenges to make sure you understand the concept you just learned. For example, a story problem about buying or selling food can help you test your ability to work with decimals.

What are the Learning Objectives for Maths in Year 2?


The learning objectives for maths in Year 2 are divided into different learning strands. Learning strands provide a clearer structure for teaching mathematics and tracking children's progress within primary learning. There are 7 learning strands for primary maths:
  • 1: Counting and understanding number including:
• Read and write two-digit and three-digit numbers in figures and words; describe and extend number sequences and recognise odd and even numbers
• Count up to 100 objects by grouping them and counting in tens, fives or twos; explain what each digit in a two-digit number represents, including numbers where 0 is a place holder; partition two-digit numbers in different ways, including into multiples of 10 and 1
• Order two-digit numbers and position them on a number line; use the greater than (>) and less than (<) signs
• Estimate a number of objects; round two-digit numbers to the nearest 10
• Find one half, one quarter and three quarters of shapes and sets of objects

  • 2: Using and applying mathematics including:
• Solve problems involving addition, subtraction, multiplication or division in contexts of numbers, measures or pounds and pence
• Identify and record the information or calculation needed to solve a puzzle or problem; carry out the steps or calculations and check the solution in the context of the problem
• Follow a line of enquiry; answer questions by choosing and using suitable equipment and selecting, organising and presenting information in lists, tables and simple diagrams
• Describe patterns and relationships involving numbers or shapes, make predictions and test these with examples
• Present solutions to puzzles and problems in an organised way; explain decisions, methods and results in pictorial, spoken or written form, using mathematical language and number sentences

  • 3: Knowing and using number facts including:
• Derive and recall all addition and subtraction facts for each number to at least 10, all pairs with totals to 20 and all pairs of multiples of 10 with totals up to 100
• Understand that halving is the inverse of doubling and derive and recall doubles of all numbers to 20, and the corresponding halves
• Derive and recall multiplication facts for the 2, 5 and 10 times-tables and the related division facts; recognise multiples of 2, 5 and 10
• Use knowledge of number facts and operations to estimate and check answers to calculations

  • 4: Calculating including:
• Add or subtract mentally a one-digit number or a multiple of 10 to or from any two-digit number; use practical and informal written methods to add and subtract two-digit numbers
• Understand that subtraction is the inverse of addition and vice versa; use this to derive and record related addition and subtraction number sentences
• Represent repeated addition and arrays as multiplication, and sharing and repeated subtraction (grouping) as division; use practical and informal written methods and related vocabulary to support multiplication and division, including calculations with remainders
• Use the symbols for adding, subtracting, multiplication and division and equals to record and interpret number sentences involving all four operations; calculate the value of an unknown in a number sentence

  • 5: Understanding shape including:
• Visualise common 2-D shapes and 3-D solids; identify shapes from pictures of them in different positions and orientations; sort, make and describe shapes, referring to their properties
• Identify reflective symmetry in patterns and 2-D shapes and draw lines of symmetry in shapes
• Follow and give instructions involving position, direction and movement
• Recognise and use whole, half and quarter turns, both clockwise and anticlockwise; know that a right angle represents a quarter turn

  • 6: Measuring including:
• Estimate, compare and measure lengths, weights and capacities, choosing and using standard units (m, cm, kg, litre) and suitable measuring instruments
• Read the numbered divisions on a scale, and interpret the divisions between them (e.g. on a scale from 0 to 25 with intervals of 1 shown but only the divisions 0, 5, 10, 15 and 20 numbered); use a ruler to draw and measure lines to the nearest centimetre
• Use units of time (seconds, minutes, hours, days) and know the relationships between them; read the time to the quarter hour; identify time intervals, including those that cross the hour
