Do these five maths challenges fill you with dread or do they seem less scary than the ones you remember from your school days?
看看下面这五道数学题，你的心里是充满了恐惧，还是觉得它们比上学时的题更简单了呢？
If you sailed through them with full marks, it's because they are from the new Asian-style maths teaching techniques that are designed to be simpler and make children sharper, with many British schools starting to weave them into their own lesson plans.
The approach focuses on deepening understanding by using physical objects and pictures to explore traditional maths symbols, as well as spending more lesson time developing reasoning and problem-solving skills.
These particular examples are from the free full curriculum that Tes - a school resource body - produces for years 1-6 of primary school. So can you figure out the answers?
Tes has launched a collection of maths education resources to help more schools looking to use the Shanghai and Singapore approach.
Tes网站已经发布了一系列数学教学资源，帮助更多学校借鉴上海和新加坡的教学方法。
Discussing the new techniques, Laura Beeson, Assistant Head Teacher at Primrose Hill Primary School in London, said: 'We are still on the start of our mastery journey.
谈到这个新方法，伦敦樱草山小学的校长助理劳拉•比森说：“我们对精熟教学法的学习还在起步阶段。”
'It is important that we don't see the Shanghai approach as simply a method that we can pick up and use in our own school settings.
“我们不应该只把上海教学法看成一个能照搬到自己学校的方法，这一点非常重要。”
'The differences both within our school systems and culture are vast. It is up to us as practitioners to look at the fundamental values of the approach and see how they can be implemented in our own UK school settings.
'As a school we have started by focusing on three of the main aspects of mastery teaching: taking slow steps and dedicating more time to concepts before moving on, the use of models and images to support understanding and the importance of variation - seeing the same concept in many different ways.
'Finding resources that contain that variation of the same concept is one of the main barriers for our teachers. The Tes primary maths mastery space is a central place to look for this - giving teachers a starting point.'
