In Australia and New Zealand, summer runs from December to February, the long school holiday and the start of the new school year. The sun is strong: the UV index often reaches extreme in the middle of the day, so children learn to check it and to put sunscreen on 20 minutes before going out and again every 2 hours. These pages use those habits for their maths.
Six pages. Page 1 shows a morning and an afternoon thermometer for four beach towns, in °C with a mark every degree: write both temperatures and how much warmer it got. Page 2 gives a week of maximum temperatures in a table: plot them as a line graph, then find the hottest and coolest days, the days of 30°C or more, the biggest rise and the cool change. Page 3 is a line graph of one hot day, every 2 hours, to read and answer questions about. Page 4 is a day of UV index readings: write each hour's category from the key, then find the highest reading and when sun protection is first and last needed. Page 5 reads a clock for when sunscreen went on and finds when it goes on again, then marks a day at the beach on a time line. Page 6 is six word problems.
Look up the day's UV index and sun protection times together (the weather forecast gives them) and compare them with page 4. Keep a class chart of the maximum each day for a week and graph it the way page 2 does. For page 5, count on in hours first, then minutes, and watch for the change from a.m. to p.m. at midday.
Check the forecast's maximum each morning for a week and write it down, then compare the hottest and the coolest day. At the beach or the pool, note when the sunscreen goes on and work out together when it is due again.

Summer temperatures in degrees Celsius, the UV index and sunscreen times on hot days at the beach. Students read thermometers, graph a week of maximums, read a hot day hour by hour, sort UV readings into categories, find when sunscreen goes on again and solve word problems.
