Summer Term – Week 2 – Measure Lesson 1: Converting metric and imperial units Star words: convert, multiply, divide, imperial, metric, approximately Metric units are units of measure such as: metres, litres and kilograms Imperial units are units of measure such as: inches, pounds and pints. Today we will practise converting from imperial into metric units and from metric to imperial units. Inches - Centimetres This sign means approximate. It is different from equals because it is not entirely accurate and is only Layer 1 -Task 1: roughly the same. - In an inch, there are _____ centimetres - In 2.5 cm there is _____ inch. Convert the measures below: Success Criteria: inches to cm Success Criteria: cm to inches Multiply number by 2.5 Divide number by 2.5 Imperial – Inches Metric - Centimetres 1 2 3 10 5.5 8 12 40 50 40 What do you notice?________________________________________________ _________________________________________________________________ Kilograms to Pounds Success Criteria: kg to lb Success Criteria: lb to kg Multiply number by 2 Divide by 2 Layer 1 - Task 2: Convert the measures below Kilograms (Kg) Pounds (lb) 1 kg 2 kg 3 kg 5 kg 10 kg 40lb 46 lb 100 kg 1005 kg 3001 lb Millilitres to Pints Task 3: Layer 2: Lesson 2: Time Week = 7 days Month = 4 weeks Star words: (approximately) Month, year, day, week Year = 12 months = 365 days Success Criteria – months to years Success Criteria – Years to months Divide by 12 Multiply by 12 Layer 1 -Task 2: Fill in the blanks below using the information above Success Criteria – Weeks to days Success Criteria – days to weeks 1. Draw out formal method 1. Write out weeks and days 2. Divide tens by 7 2. Multiply weeks by 7 (because 3. Divide ones by 7 there is 7 days in one week) 4. Write remainders 3. Add on extra days 5. Put together total weeks and 4. Write out total days days (remaining amount) Layer 2: Aisha is 10 years and 5 months old. Her brother Amit is 6 years and 11 months old. How much older is Aisha in years and months? A child’s school year has 38 school weeks of 5 days. In a non-leap year, how many days does each child not have to go to school? A family has lived in a house for 12 years and 7 A leap year occurs every four years. This is when the rotation months. They want to have a party to celebrate 20 of the Earth is slightly longer years of living in the house. How many months will they and February has an extra day. have to wait until the party During these years, there are 366 in a leap year. Lesson 3: Time 60 seconds = 1 minute Star words: 60 minutes = 1 hour time, second, minute, hour, day 24 hours = 1 day Layer 1 – Task 1: Fill in the stem sentences below: 60 minutes 1 hour = ____ minutes ½ hour = _____ minutes 30 minutes 30 minutes ¼ hour = _____ minutes 15 mins 15 mins 15 mins 15 mins Layer 1 – Task 2: 1. Rewrite three hundred and eighty-six minutes in hours and minutes. 2. What is seven years and eleven months in months alone? 3. Isabella swims 4 lengths of a swimming pool. Her target is to swim the lengths in under 5 minutes. It takes her 319 seconds. Explain why Isabella did not achieve her target. 4. A year 6 class has 5 maths lessons during the week. Each lesson lasts 1 hour and 15 minutes. How many hours and minutes will they have maths lessons in a seven-week half term? Layer 2: Anna and James are training for a school athletics competition Layer 3: Optional Extension Lesson 4: Telling the time Star Words: past, to, o’clock, analogue, minute, hour Watch these video’s as a reminder to telling the time with an analogue clock: https://www.youtube.com/watch?v=qi6OyVJvi6A https://www.youtube.com/watch?v=ub62GCUMZZo Remember: - Between each number on a clock face, there are five minutes. - The bigger hand on a clock measures the minute. - The smaller hand on a clock measures the hour. - As more minutes pass in an hour, the hour hand will move closer to the next digit. E.G. When it is half-past one, the hour hand will be in between the one and the two because thirty minutes have past since one o’clock but it is still thirty minutes until the next hour which is two o’clock. Layer 1 -task 1: Write the time on the analogue clocks below using the Vocabulary past or to, 1) 2) 3) Write the time of the activities below Layer 2 – task 2: Part 2 Watch these videos which recap on digital time. https://www.youtube.com/watch?v=ENOYemdWU08 https://www.youtube.com/watch?v=IBBQXBhSNUs Layer 1 – Task 2: Using the clocks in part one (above), look at each time and write in the digital representation below. Success Criteria: Example Write the hour (where the short hand is pointing to) Write your two dots (the colon) Write your minutes (where the long hand is pointing to) 08:15 Layer 2: Lesson 5: Converting time Star words: time, analogue, digital, clock - We use clocks to measure time. - We can write/read time using 12-hour clock or the 24 hour clock - We can read time on a digital clock or an analogue clock. This is a digital clock This is an analogue clock - We can read digital time using the 24-hour clock or the 12-hour clock - We read analogue time using only the 12-hour clock. Watch this video to show you how to tell the time in 24 hour clock. https://www.youtube.com/watch?v=QvPe0pSZalk Layer 1 – Task 1: Fill in the missing times in the grid below. Success Criteria 1. Write time in 12 hours clock 2. If it’s am, add a zero first 3. If it’s pm, add 12 4. Add dots and zeros to show it is on the hour (O’clock) 12-hour 24-hour 12-hour 24-hour Example using clock (am) clock clock (pm) clock success criteria: 12am 00:00 12pm 12:00 1am 01:00 1pm 13:00 02:00 14:00 1). 3pm 3am 03:00 15:00 2). Don’t need to do 04:00 4pm this step as it is pm 5am 5pm 6am 18:00 3) 3 + 12 = 15 07:00 7pm 19:00 4) 15:00 8am 8pm 9am 9pm 10am 10:00 22:00 11am 11pm Layer 1: Task 2: Convert these times from analogue to digital 24- hour time .
