P3b Numeracy – Thursday 21.1.2021CylindersWarm up: Count forwards and backwards in 3s (up to 30) and in 4s (up to 40). If you manage to remember all the numbers correctly you could try counting a bit higher. You can try tapping on the numbers as you go along using ‘Paint the squares’ () until you can remember them all without looking.In 3s: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30In 4s: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 Watch the cylinders’ video for today on adding and subtracting 10s.Work out these addition and subtraction problems, adding in 10s.40 + 10 =70 + 20 =50 – 20 =60 + 10 =50 + 30 =30 – 20 =30 + 10 =40 + 40 =70 – 40 =50 – 10 =20 + 50 =60 – 50 =80 – 10 =10 + 80 =100 – 70 =60 – 10 =30 + 70 =90 – 60 = Play the ‘Hit the Button’ game by selecting ‘Number Bonds’ and then ‘Addition within 100 (tens)’ up: Start by counting forwards and backwards to 50.Then can you sequence these numbers from smallest to biggest?25, 27, 23, 26, 24, 224. 11, 9, 12, 7, 10, 813, 16, 11, 14, 15, 125. 29, 32, 31, 28, 30, 2722, 19, 20, 18, 21, 236. 37, 34, 36, 35, 38, 33Play this game to practise recognising odd and even numbers:*ReminderEven numbers: all numbers ending in 0, 2, 4, 6, 8Odd numbers: all numbers ending in 1, 3, 5, 7, 9Watch the cubes’ video for today on sharing into equal groups.Use some beans/pasta/counters or something else you have a lot of at home to make these groups. Record your answers by writing: e.g. 3 groups of 2 = 6Share 18 between 6 groups. How many in each group?Share 36 between 4 groups. How many in each group?Share 30 between 10 groups. How many in each group?Share 35 between 5 groups. How many in each group?Share 12 between 6 groups. How many in each group?Share 40 between 5 groups. How many in each group?Share 36 between 6 groups. How many in each group?Share 32 between 4 groups. How many in each group?SpheresWarm up: Count forwards and backwards in 3s (up to 30) and in 4s (up to 40) If you manage to remember all the numbers correctly you could try counting a bit higher. You can try tapping on the numbers as you go along using ‘Paint the squares’ () until you can remember them all without looking.In 3s: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30In 4s: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 *You can practise writing down the numbers as well.Watch the spheres’ video for today on subtracting from a decade using facts to 10.Work out these subtraction problems using your facts of number bonds to 10.20 – 3 =60 – 6 =90 – 9 =30 – 5 =30 – 7 =80 – 3 =40 – 2 =50 – 8 =60 – 8 = 70 – 4 =40 – 7 = 100 – 4 =**ChallengeCan you work these problems out using your number bonds to 10?150 - 4 = 620 – 6 =940 – 9 =230 – 7 =380 – 8 =760 – 5 =CuboidsWarm up: Use your fingers to keep track and count the number of jumps counting forwards starting and stopping at these numbers.From: 27 to 35, 31 to 40, 73 to 79, 56 to 61, 42 to 52, 87 to 94, 68 to 77, 93 to 100, 75 to 82, 86 to 91.Can you check again and see if you can count the jumps again without using your fingers but you number bonds and facts?Watch the cuboids’ video for today on counting items in equal groups.Share 9 equally between 3. How many in each share?Share 24 equally between 4. How many in each share?Share 15 equally between 5. How many in each share?Share 30 equally between 5. How many in each share?Share 12 equally between 4. How many in each share?Share 21 equally between 3. How many in each share?Share 20 equally between 2. How many in each share?Share 16 equally between 2. How many in each share?Share 18 equally between 3. How many in each share?Share 20 equally between 5. How many in each share?Use some pasta/beans/counters from your home pack or anything else that you have at home to share them into groups equally and work out how many are in each group you made. Record your answers like this: 3 lots of 5 = 15 or 3x5 = 15. ................
