2. 2. © www.teachingpacks.co.uk Scales are used to measure the mass of different items. We can use a measuring cylinder to measure amounts of liquid. Rulers and tape measures are used to measure length. We also use rulers to draw straight lines. Clocks and stopwatches are used to tell and measure the time. An abacus has sets of 10 beads on rods. It is used for counting and other calculations. A calculator can work out calculations quickly. Make sure that you press the right keys and check the answers against your estimate! Maths Equipment A thermometer is used to measure the temperature. Protractors are used for measuring and drawing angles.

3. 3. Place Value Place value tells us how much each digit is worth in a number. © www.teachingpacks.co.uk M 100 Th 10 Th Th H T U Millions Hundreds of Thousands Tens of Thousands Thousands Hundreds Tens Units 1, 6 5 9, 0 2 3 If you are not sure what a number is, write the headings above each digit to help you. This number has seven digits.
4. 4. Square Numbers When a number has been multiplied by itself, we say that the answer is a square number. Can you see why they are called square? The ﬁrst ten square numbers are 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100. We can write four squared as 4 x 4 or 42. © www.teachingpacks.co.uk 1 x 1 = 1 2 x 2 = 4 3 x 3 = 9 4 x 4 = 16 5 x 5 = 25 A square root is the opposite of a square number. If 4 x 4 = 16, the square root of 16 is 4. We use the square root sign (√) to show this, so √16 = 4
5. 5. Addition Addition is counting up or ﬁnding the total of some numbers. Here are some more words that are linked to addition: add more plus increase total sum altogether © www.teachingpacks.co.uk 5 6 7 8 9 100 1 2 3 4 5 + 3 = 8 We can use a number line to help us count on. ++ + + The addition sign

If they are not the same length, it is irregular. © www.teachingpacks.co.uk 3 equal sides Regular Triangle 4 equal sides Regular Quadrilateral 5 equal sides Regular Pentagon 7 equal sides Regular Heptagon 8 equal sides Regular Octagon 9 equal sides Regular Nonagon 10 equal sides Regular Decagon 6 equal sides Regular Hexagon

9. 9. Analogue Clocks The longer hand on a clock tells us the minutes. The shorter hand tells us the hours. © www.teachingpacks.co.uk ClockwiseAnticlockwise o’clock ﬁve past ten past quarter past twenty past twenty-ﬁve pasthalf past twenty-ﬁve to twenty to quarter to ten to ﬁve to Midday 12 o’clock in the middle of the day (or noon). Midnight 12 o’clock at night. What time does this clock show? Which way do the hands of a clock go round? Photo: © ThinkStock
10. 10. Temperature Temperature is a measure of how hot or cold something is. We measure temperature using a thermometer. We usually measure temperature in ºC (degrees Celsius) but it can also be measured in ºF (degrees Fahrenheit). Did you know? Water freezes at 0ºC and it boils at 100ºC. © www.teachingpacks.co.uk Photo: © ThinkStock
11. 11. Pie Chart Pie charts are used to compare information. A pie chart looks like a pie that is split into slices. In this survey, 16 people chose their favourite sport.

Which was the least popular? © www.teachingpacks.co.uk Tennis 3 Basketball 2 Football 7 Netball 3 Cricket 1 Our Favourite Sports Cricket Tennis Basketball Netball Football
