Be sure you have your older child take the placement test for singapore math, because it is much different from other programs. The tests are for the Primary series.

There is no test for the Earlybird Series, but here is a list of skills covered in EarlyBird 2A and 2B, from the Little Hearts intro. If you feel your younger is past that, you should test her, too, for placement in the Primary series.
Math Exploration
Daily math lessons are included in the “Learning the Basics” part of the
plans. These activities use concrete objects and hands-on experiences
to introduce mathematical concepts through guided play. The workbooks
Earlybird KIndergarten Mathematics 2A & 2B by Winnie Tan provide a
text connection for each math lesson. Two of the lessons in each unit
require these math texts. If you do not have the texts, you will need to
skip those lessons in the plans.
A brief scope and sequence of the math concepts is listed by unit below
(Number ‘1’ corresponds to unit 1, number ‘2’ corresponds to unit 2, etc.):
1 - counting and writing numbers ‘1’-’5’
2 - counting and writing numbers ‘1’-’5’, introduction of ‘6’-’10’
3 - counting and writing numbers ‘6’-’10’
4 - counting sets with one more, same number, or one less
5 - comparing sets: greater than, less than, one to one
6 - comparing numbers, identifying characteristics of basic shapes
7 - sorting by attributes, finding common attributes, and patterns
8 - patterns, sizes: big, medium, small
9 - ordering by height, measuring and comparing lengths
10 - nonstandard measurement: estimating, measuring length & width
11 - comparing nonstandard measurements, estimating weights
12 - capacity: filling, emptying, graphing, one to one correspondance
13 - oral counting forward and backward, number words
14 - counting, matching, and tracing numbers and number words ‘0’-’10’
15 - ordinal numbers, number words, introduction of tens and ones
16 - counting and reading numbers up to ‘20’, groups of ones and tens
17 - counting and writing numbers ‘11’-’20, number words ‘11’-’20’
18 - fractions: one-half, one-quarter
19 - left/right directionality, adding ‘1’-’10’ by counting on a number line
20 - combining two sets together to add
21 - combinations that make ‘6’-’9’
22 - combinations that make ‘10’, number sentences, separating sets
23 - comparing sets, subtracting: counting back, taking away
24 - subtraction: crossing out, stories, separating one group into two
25 - separating one set into two, horizontal and vertical subtraction
26 - missing numbers, picture stories, comparing numbers

34 - introduction to quarters, solid shapes: cylinder, cube, rectangular
solid
I want to encourage you that Carrie's hands-on activities make it easy to teach singapore. Little Hearts has hands on activities for Earlybird 2A and 2B. Beyond Little Hearts has hands-on activities for Primary 1A and 1B. Bigger Hearts has hand on activities for Primary 2A and 2B, which is what my 3rd grader is using. With the hands on activities, you only need the workbooks for the level you are using, and not the textbooks.
Singapore took some getting used to, but my girls are now thriving on it
It is a great program and very appropriate for K or 1st. I would just let them keep advancing up the program together using math and LA for their individual levels. Honestly, you could go either way....I was just thinking that with little ones, it might be easier to have some subjects combined.
