What do children learn in math in 2nd grade of Primary school?
In second grade the child reads, composes and decomposes natural numbers up to 999 into hundreds, tens and units, places them on the number line and compares them. They add and subtract with carrying and with complete hundreds, and estimate quantities before calculating. They know the 1 and 2 euro coins and the 5, 10, 20, 50 and 100 euro banknotes and their equivalences, use the metre, the kilogram and the litre, read the calendar (year, month, week, day) and interpret simple graphs such as pictograms and bar charts.
About the curriculum: the minimum teaching requirements for Primary Education Mathematics (Royal Decree 157/2022, of 1 March, BOE no. 52, of 2 March 2022) set the basic knowledge by two-year cycles, not course by course: this year belongs to the first cycle (1st and 2nd grade), and the distribution of the content between the two years of the cycle is our own. Each autonomous community completes this national minimum with its own curriculum. The basic knowledge, quoted verbatim, is in the section below.
