D o t t i e D o u b l e	Problem 1:Computer conundrum	a	a
	Only one	Add 1 to any integer.	Ma2 2a count on from any 2- or 3-digit number.
	Numb numbers	Read and write whole numbers to at least 10,000 in figures and words, and know what each digit represents.	Ma2 2c read and write whole numbers, recognising that the position of a digit gives it its value.
	Doubling dilemmas	Derive quickly addition doubles.	Ma2 3g double and halve any 2-digit number.
	Problem 2:Dottie's database	Solve a problem by interpreting data in tables, charts, graphs and diagrams including those generated by a computer.	Ma3 1a select and use handling data skills when solving problems in other areas of the curriculum; 2a solve problems involving data
S a m L a v a	Problem 1:Open sesame	Recognise and extend number sequences formed by counting from any number in steps of constant size.	Ma2 2a recognise and continue number sequences formed by counting on or back in steps of constant size from any integer.
	Problem 2:Symmetry power	Sketch the reflection of a simple shape in a mirror line parallel to one side, where the lines of the pattern are parallel or perpendicular to the mirror line.	Ma3 1c approach spatial problems flexibly, including trying alternative approaches to overcome difficulties; 3c make and draw with increasing accuracy 2-D patterns.
