In our literacy time today we wrote letters about ourselves, practising our letter writing skills. After that we looked at number sequences in maths. We learned about the sequence of triangular numbers. You can see the first four triangular numbers on the board above. You can find any triangular number by adding 1, multiplying, and dividing by 2. For example, the tenth triangular number is found by multiplying 10 x 11, and then halving the answer. It is 55.
