Problem-solving Investigations - Year 1/2
Children use digit cards to make two-digit numbers between neighbouring multiples of 10.
Stop me if you can! (Y1): Children create diagonal lines on a 1 - 100 grid by adding and subtracting 10 and 1, whilst trying to stop their partner doing the same. Jack's amazing beanstalk (Y2): Children double numbers and add to a running total, and then look for patterns.
Y1: Children add single-digit numbers to numbers between 30 and 40, aiming to bridge 40. Y2: Children look for numbers which have a difference of 5.
Children explore the number of half past or quarter past and quarter to times in a day by looking at the two sides of the clock.
Children use the same size 'carriages' (rods) to make a 'train' of 20 units.
Dicey coins (Y1): Children roll a dice to determine how many coins they can take. They try to choose coins with a total of either 10p or 20p. Sixteen rocks (Y2): Children arrange place value cards to make three-digit numbers and then add the digits. They look at patterns.
Y1: Children use dominoes to generate two-digit number plus one-digit numbers additions in a pattern. Y2: Children use dominoes to generate pairs of numbers with a given total.
Children find out which letter is used most often in a page-a-day diary which uses shorthand for each month.
Children investigate which numbers from 1 to 20 (Y1) or 50 (Y2) will give the longest halving chain (each 'link' must be a whole number).
Children find different ways of getting 1p, 2p, 3p...change when buying cakes costing 1p to 20p and using 2p, 5p, 10p or 20p coins.
Time challenge (Y1): Children use time vocabulary to write times on analogue clocks. Make it equal (Y2): Children find pairs of numbers to satisfy an equality.
