This presentation provides five days of teaching that cover the objectives: • Revise placing 2-digit numbers on lines • Place 3-digit numbers on lines It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards. Although column subtraction is specified for Year 3 in the National Curriculum, Hamilton believe that teaching column subtraction in Year 4 will be more successful. The National Curriculum Guidance specifies that teachers can teach areas of study in different year groups than those mentioned in the Curriculum, so long as they are taught within the same Key Stage. If you would like to teach column subtraction in Year 3 please see Year 4 Addition and Subtraction autumn Unit 7, spring Unit 4 and summer Units 2 and 3. Day 1 Teaching Write 137 – 72. Agree we can use Frog to find this difference, by, counting up from 72 to 137. Draw an empty number line jotting to show this and model each of Frog’s jumps (72 to 80, 80 to 100 and 100 to 137). Explain that we can do 1 big jump to 100. Repeat to model using Frog to do £1.46 – 83p. Children try £1.23 – 88p. Day 2 Teaching Display a word problem resulting in the calculation 476 – 438. How can Maths Frog help us to work this out? Frog will start on 438, jump to the next 10 (440), then jump to 470, then 476. Remind children that we could do one big jump of 36 from 440 to 476 if we are confident but we don’t have to! Children try 873 – 837. Day 3 Teaching Show a toy priced £4.67. Give a child a £5 note and ask them to use this to pay for the toy. You’ve given the shopkeeper too much money. How will she work out how much change to give you? Maths Frog can help us! Sketch a line from £4.67 to £5. Model using Frog to hop to £4.70 and then to £5. Repeat, to find change from £10 and £20. Day 4 Teaching Show a game and say that it costs £18. So far Katie has saved up £7.55. How much more does she need? Maths Frog can help! Sketch a line from £7.55 to £18. Model the hops from £7.55 to £7.60, then to £8, then to £18. Ensure children add hops accurately to find the answer: £10.45. Repeat as necessary for finding the difference between £8.43 and £14, then £6.55 and £19. Day 5 Teaching A family have £100 and so far have spent £67.73. How much money is left? Use Frog to model the hops. Ask children to add the jumps, adding the £s first then the pence, then put them together. Some children may draw 3 hops, others draw 4. It doesn’t matter as long as we get the right answer! Repeat for a family who have spent £62.41 out of their £100. This teaching is part of Hamilton’s Year 5 Decimals and Fractions block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.

This presentation provides five days of teaching that cover the objectives: Using place value to add/subtract It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards. Day 1 Teaching Display a place value grid and write 3-digit numbers on it. Show which digit changes if you add multiples of 10. Repeat to show which digit changes if you add multiples of 100. Repeat for 1s. Day 2 Teaching Use a place value grid to show which digit changes if you subtract multiples of 10. Repeat for multiples of 100 or 1. Day 3 Teaching Demonstrate how to add and subtract near multiples of 10 to/from 2-digit numbers using a number line, and also a 1-100 number grid. Day 4 Teaching Use an empty number line to model the hops involved in adding a near multiple of 10 to a 3-digit number: 225 + 29 is 225 hop 30 along and then back 1, etc. Day 5 Teaching Use an empty number line to model the hops involved in subtracting a near multiple of 10 from a 3-digit number. Demonstrate how we adjust the hops to subtract 51 or 49 rather than 50. This teaching is part of Hamilton’s Year 3 Place Addition and Subtraction block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.

This presentation provides three days of teaching that cover the objectives: Mental subtraction – counting up It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards. Day 1 Teaching Remind children of Maths Frog. Demonstrate how we can count up along an empty number line using Frog to work out the difference between 87 and 102. Model several subtractions. Day 2 Teaching Demonstrate counting up using Frog hopping along a number line to show how we calculate 113 – 78. Stress how we add the hops to find the answer. Day 3 Teaching Use Frog and the empty number line to perform subtractions (112 – 76) and make deliberate errors which children have to correct. This teaching is part of Hamilton’s Year 3 Addition and Subtraction block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.

This presentation provides two days of teaching that cover the objectives: Rehearse 24 hour clock Time intervals It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards. Day 1 Teaching Revise 24-hr clock using a train timetable and relating times to the school day. Convert 24-hour clock times to am and pm times and vice versa. Count in steps of 1 hour on a counting stick from different starting times, through midday and midnight. Day 2 Teaching Visit an online TV guide. Children write start times using 12-hour format (they are in 24-hour format on the website). Children find programmes lasting less than half an hour, then those lasting more than half an hour. Scroll for a programme crossing an hour. Sketch a time line jotting to show how to find the length of this programme. Repeat. This teaching is part of Hamilton’s Year 4 Measures and Data block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.

This presentation provides two days of teaching that cover the objectives: Units of time Timing events and recording data Interpret results It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards. Day 1 Teaching Four children write their name 20 times and four others time them. Record times in a table. Discuss how we can draw a bar chart to represent this data. What scale shall we have? Try 1 step = 5 or 10 seconds. Which will fit on the page but not look too small? Discuss and draw a bar chart. Discuss questions that could be asked about the data. Children then write their name 10 times and record the time. Day 2 Teaching Show children the table showing the number of children that were born in the first 7 months of the year. Discuss this. Say that we will represent this information in a pictogram – one picture represents four units. Draw this together. This teaching is part of Hamilton’s Year 4 Measures and Data block.
