Here are some standards, objectives etc for use as reference. You can click on any of the objctives to create a lesson plan out of it.
Std 1.1 1.1 Students understand how to name, represent and use numbers to 100. Using concrete objects, they appreciate the sizes of these numbers and build their mental images.

Std 1.2 They count and group objects in ones and tens and understand that a 2-digit number has a tens value and a ones value and build an understanding of the concept of place value (in base ten number system) i.e. the place of a digit gives its value. They are able to represent numbers on an abacus i.e. decompose and compose numbers using place-value. They use place value to order numbers to 100 in ascending and descending order (excluding symbols).

Std 2.1 Students understand and learn how to name and represent numbers to 1000 and note the pattern in their representation. They appreciate relative sizes of the numbers by regarding 10 as a unit or hundred as a unit (in concrete manipulation or mental images).

Std 2.2 They compose and decompose (expand) numbers using place value. They recognize representations using ones blocks, tens blocks, hundreds blocks and write numbers for these representations.

Std 2.3 They compare and order the numbers on a partial number line and understand their relative position. They order them in ascending and descending order using symbols >, <, = .

Std 2.4 They count backward and forward starting from any number to 1000. They know ordinal numbers to 20 and use them in different contexts.

Std 2.13 They know and recognize odd and even numbers.

Std 2.15 Estimation - estimate number of objects in a set of upto 50 objects, count and compare the estimate with the actual number - check reasonableness of addition/subtraction answers

Std 3.1 Students extend naming and representation of numbers to 10000. They understand the cyclical pattern in which the digits change as the numbers increase and realize that counting can go on endlessly in this fashion. They deepen their understanding of whole numbers, their representation and their relative sizes.

Std 3.2 They understand the place-value structure of the base-ten number system and are able to efficiently decompose (expand) and compose numbers using place value. They recognize equivalent expanded representations for the same number and compare and order the numbers.

Std 3.3 They recognize representations using ones blocks, tens blocks, hundreds blocks and thousands blocks and write numbers for the same correctly.

Std 3.25 Estimation - estimate number of objects in a set of upto 100 objects, count and compare the estimate with the actual number - use properties of operations and their mutual relation to check reasonableness of results

Std 4.1 Students deepen their understanding of whole numbers by knowing number representation to 100000 and may be, beyond. They summarize the decimal numeration system and understand the relative sizes of the numbers.

Std 4.2 They decompose and compose numbers using place value and are able to efficiently compare and order.

Std 4.18 Estimation - estimate number of objects in a set of upto 500 objects and count and compare the estimate with the actual number - understand meaning and purpose of round numbers i.e. why rounded solutions may be appropriate and when they are called for - know how to round 2-digit number to the nearest 10, 3-digit number to the nearest 100 and 4-digit number to the nearest 1000
